Answer:
The first 3x^2 + 2x is a second degree polynomial, so it's a quadratic binomial (2 terms). The second 2x^2 - 5x + 3 is a second degree trinomial (3 terms), and the third is a monomial (1 term). Not sure if that's what you were looking for.

Step-by-step explanation:
In a certain sock drawer, there are 4 pairs of black socks, 3 pairs of gray socks and 2 pairs of orange socks. If socks are removed at random without replacement, what is the minimum number of socks that must be removed in order to ensure that two socks of the same color have been removed
Answer:
4 socks.
Step-by-step explanation:
There are three different colors of socks in the drawer: black, gray and orange.
The worst possible scenario for making a pair would be getting a different color of sock with the first three picks (1 black, 1 gray, 1 orange). Since we now have one of each, the next sock drawn from the drawer will form a pair with one of our three socks. Therefore, the minimum number of socks that must be removed in order to ensure that two socks of the same color have been removed is 4.

The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where x
represents the smaller integer. Which equation can be factored and solved for the smaller integer?
O2 + x - 72 = 0
O2 + x + 72 = 0
x2 + 2x - 72 = 0
x2 + 2x + 72 = 0
Answer:
[tex]\boxed{\sf \ \ \ x^2 + x -72 = 0 \ \ \ }[/tex]
Step-by-step explanation:
Hello,
We need to use the distributive property which means that for a, b and c real numbers a(b+c)=ab+ac
So here we can write
[tex]x(x+1)=72\\<=> x*x+x*1=72\\<=> x^2 + x -72 = 0\\[/tex]

I don't know why its correct. Help explain to me pls.
The rectangle they give you is 12 units tall. This is the result of scaling by a factor of 1.5, ie it is 1.5 times taller than what the answer will be. Let the answer rectangle have a height of h. This means h*1.5 = 12, or 1.5h = 12
Divide both sides by 1.5 to find that h = 8. The answer rectangle's height is 8 units.
The width's will be treated in a similar manner. I picked on the height since it's easier to see that the height lines up with 12 (the width seems to be between 2 and 4, but its not clear if its at the midpoint).

Help please.... what is the solution of sqrt -4x=100? A- x=-2500 B-x=-50 C-x=-2.5 D-no solutions
Answer:
A. x = -2,500.
Step-by-step explanation:
sqrt(-4x) = 100
(sqrt(-4x)^2 = (100)^2
-4x = 10,000
4x = -10,000
x = -2,500
Check your work...
sqrt(-4(-2,500))
= sqrt(4 * 2,500)
= sqrt(10,000)
= plus or minus 100
A. x = -2,500 is your answer.
Hope this helps!
Answer:
The answer would be A, x=-2500
Explanation:
To remove the radical on the left side of the equation, square both sides of the equation.
√ − 4 x^ 2 = 100^ 2
Simplify each side of the equation.
− 4 x = 10000
Divide each term by
−4
and simplify.
x = -2500

please help me answer this question Solve: y − x = 12 y + x = -26 (19, -7). (-7, 1). (7, 19). (-19, -7).
Answer:
(-19 , -7)
Step-by-step explanation:
y - x = 12
y + x = -25 we sum them to get
2y = -14 , y = -7
then we put -7 instead of y in any of the equations:
-7 - x = 12
-x = 19
x = -19,
finally (x , y) is (-19 , -7)

Bruhhh I need help dude !!!
Answer:
(B), in which the first two values are 2 and 10.
Step-by-step explanation:
We can tell that this is a proportional relationship because we can examine the numbers in there.
(2,10)
(4,20)
and (6,30).
If you notice, the x value times 5 gets us the y value for every single point there.
Therefore, B is proportional and it's equation is y = 5x.
Hope this helped!
Answer:
B.
Step-by-step explanation:
B. Is the only one that proportional because,
(2,10)
(4,20)
(6,30)
All these x values multiply by 5 to get the y value.
So the equation is y = 5x meaning it is linear and it goes through the origin which makes it proportional.
Thus,
answer choice B is correct.
Hope this helps :)
find the solutions of x and y.
Answer:
x = 15, y = 4
Step-by-step explanation:
By Basic proportionality theorem, we have:
x/ 5 = 18/6
x = (18*5)/6
x = 90/6
x = 15
Again By Basic proportionality theorem, we have:
12/y = 18/6
y = (12*6)/18
y = 72/18
y = 4

Answer:
397.7 m²
Step-by-step Explanation:
The are of ∆UVW can be found ones we know the measure of 1 angle that is in between known lengths of two sides. Then, we would apply the formula, ½*a*b*sin(θ)
Where, a and b, are the lengths having an included angle (θ), in between them.
To find area of ∆UVW, we need m < V, side lengths of UV and VW.
m < V = 113°
VW = 29 m
UV = ?
Step 1: find UV using the Law of sines
[tex] \frac{UV}{sin(W)} = \frac{VW}{sin(U)} [/tex]
W = 34° [180 - (113+33)]
U = 33°
VW = 29 m
UV = ?
[tex] \frac{UV}{sin(34)} = \frac{29}{sin(33)} [/tex]
Multiply both sides by sin(34)
[tex] \frac{UV*sin(34)}{sin(34)} = \frac{29*sin(34)}{sin(33)} [/tex]
[tex] UV = \frac{29*sin(34)}{sin(33)} [/tex]
[tex] UV = 29.8 m [/tex]
Step 2: find the area of the triangle
Area = ½*a*b*sin(θ)
a = 29.8 m
b = 29 m
θ = 113°
Area = ½*29.8*29*sin(113)
Area = 397.7 m² (nearest tenth)

Answer:
Choice A
Step-by-step explanation:
First, let's simplify the equation. We get [tex]\frac{3^{-3}m^{6} n^{-3}}{6mn^{-2} }[/tex] . Then, we can simplify. We now have [tex]\frac{3^{-3}m^{5} }{6n}[/tex] . To get rid of the negative exponent, we multiply the top and bottom by 3^3 to get [tex]\frac{m^{2} }{6nx3^{3} }[/tex]. Note that the x in the denominator stands for multiplication. 3^3 = 27, so we have [tex]\frac{m^{5} }{6n(27)} = \frac{m^{5} }{162n}[/tex]
Answer:
m^5/ 162 n
Step-by-step explanation:
( 3 m^-2 n) ^-3 / (6mn^-2)
We know a^ -b = 1/ a^b
1 / ( 3 m^-2 n) ^3 *(6mn^-2)
Distribute the power of 3
1 / ( 3^3 m^ -2 ^ 3 n^3) * ( 6m n^-2)
We know a^ b^ c = a^ ( b*c)
1 / ( 27 m^( -2 * 3) n^3) * ( 6m n^-2)
1 / ( 27 m^( -6) n^3) * ( 6m n^-2)
We know a^b * a^c = a^ ( b+c)
1 / ( 27*6 m^( -6+1) n^(3-2))
1/ (162 m^ -5 n^1)
We know a^ -b = 1/ a^b
m^5/ 162 n
what is the quotient of 1 and 2/3 divided by 4/5
Answer:
2 and 1/12
Step-by-step explanation:
1 and 2/3 = 5/3.
when dividing fractions, invert and multiply.
5/3x5/4=25/12
=2 and 1/12
Answer:
The quotient is:
2 and 1/12
Step-by-step explanation:
1 and 2/3 = 1 + 2/3
1 = 3/3
1 + 2/3 = 3/3 + 2/3 = (3+2)/3 = 5/3
1 and 2/3 divided by 4/5 is:
(5/3) / (4/5) = (5*5) / (3*4) = 25/12
25/12 = 24/12 + 1/12 = 2 + 1/12 = 2 1/12 = 2 and 1/12

Answer:
In Grade 8, 17% of students like running.
Step-by-step explanation:
Let's do process of elimination.
For the first choice, we have that In Grade 8, 14 students liked swimming. This is wrong because based on the two-way frequency table, we are dealing with decimals, which can written as percentages. Also, you can't have 0.14 of a person.
Therefore, the first choice is incorrect.
Now for the third choice. The statement is that in Grade 9, 31 percent of students liked volleyball. Okay, so we have a percentage this time. That is a good thing, but we have to know what this percentage means. This answer is incorrect because 31 percent goes with the column of running, not volleyball. It would also be a marginal frequency as well. The 31 percent actually means that 31 percent of all students in both grades liked running. In other words, a total of 31 percent of students in both 8th and 9th grade liked running.
Therefore, the third choice is incorrect.
For the last choice. The statement is 22 students like volleyball. Just like the first choice, we are dealing with percentages, not people.
Therefore, the last choice is incorrect.
Now for the second choice. We are given that in Grade 8, 17 percent of students liked running. We have a percentage, so that is good. This choice is correct because if you were to go to Grade 8 and running. Draw some lines down. You do get to 17 percent. This 17 percent means that 17 percent of students did actually like running. It also means that out of all 8th graders, 17 percent enjoyed running.
Therefore, the second choice is correct.

hi :) how to do the last part?
Answer: 1200
Step-by-step explanation:
as t → ∞, the e-value will get very very very small and be considered insignificant. In other words, as t → ∞, e → 0.
600(2 + 0) = 1200
Furthermore, if you graph this equation, you will see that the asymptote is: y = 1200. So, the y-value will get really close to 1200 but will never actually reach this value.
