Answer:
C. 19a + 11b
Step-by-step explanation:
Distribute into the parentheses.
3(5a + b) + 4(a + 2b)
= 15a + 3b + 4a + 8b
Add like terms.
15a + 3b + 4a + 8b
19a + 3b + 8b
= 19a + 11b
Hope that helps.
Hey there!
“Simplify 3(5a + b) + 4(a + 2b)”
FIRST you have to DISTRIBUTE
3(5a + b) + 4(a + 2b)
3(5a) + 3(b) + 4(a) + 4(2b)
3(5a) = 15a
3(b) = 3b
4(a) = 4a
4(2b) = 8b
“15a + 3b + 4a + 8b”
SECOND: COMBINE your LIKE TERMS
(3b + 8b) + (15a + 4a)
(3b + 8b) = 11b ⬅️ BACK number
(15a + 4a) = 19a ⬅️ FRONT number
ALL OF YOUR TERMS/NUMBERS ARE POSITIVE SO WE DON’T HAVE TO FIX ANYTHING
Answer: C. 19a + 11b ☑️
Good luck on your assignment and enjoy your day!

Answer:
d 4x^2 + 24x - 8
Step-by-step explanation:
Perimeter of the rectangle = 2x² - 5 + 12x + 1 + 2x² - 5 + 12x + 1
= (2x²+ 2x²) + (12x+ 12x) + (- 5 + 1 - 5 + 1)
= 4x² + 24x - 8

3.2 worksheet angles
Answer:
x = 28, y = 23
Step-by-step explanation:
in keeping with working only with the expressions which have the variable 'y'
the 3y angle forms a linear pair with the angle which is corresponding to the 5y-4 angle
therefore, we can say that 5y - 4 = 180 - 3y
solve for 'y': 5y - 4 = 180 - 3y
8y = 184
y = 23
Substitute to find measure of angle 5y-4: 5(23) - 4 = 111 degrees
Now we know that 2x + 13 has to equal 180 - 111 or 69 degrees
solve for 'x': 2x + 13 = 69
2x = 56
x = 28
write the explicit formula for the geometric sequence 64,32,16,8
Answer:
[tex]a_{n}[/tex] = 64 [tex](\frac{1}{2}) ^{n-1}[/tex]
Step-by-step explanation:
The explicit formula for a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 64 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{32}{64}[/tex] = [tex]\frac{1}{2}[/tex] , then explicit formula is
[tex]a_{n}[/tex] = 64 [tex](\frac{1}{2}) ^{n-1}[/tex]

A triangle can have side length of 3, 2, and 4.
O True
False
Answer: True
True because not all sides have to be equal in any shape except a square.
Answer:
True
Step-by-step explanation:
Use the triangle inequality theorem, which states that the sum of any 2 sides of a triangle has to be greater than the length of the third side.
Test out the theorem by adding together the side lengths:
3 + 2 > 4
4 + 2 > 3
4 + 3 > 2
Since all of these are greater than the other side length, this statement is true.
Given k||w, x||tm, and <5=45 degrees, what is m<7?
Answer:
∠ 7 = 45°
Step-by-step explanation:
∠ 5 and ∠ 7 are vertical angles and congruent, then
∠ 7 = ∠ 5 = 45°
what is the slope???????
Which can be used to describe the expression? Check all that apply.
Answer:
B and D
Step-by-step explanation:
One thing is for certain. The final answer will be 1/r^12 or r^(-12)
When written as the given of (r^-4)^3, the powers are multiplied.
The first one is false. There are 4 factors of r^-4 If you get an answer that says it is true, then the question means that r^-4 is 3 equal factors of r^-12
B is true
C: not true. The exponents are multiplied, not added.
D is true
E: not true. This is the same thing as C.

a) 4p+2p-3p
=> 6p-3p
=> 3p
b) 9s-5s+2s-s
=> 4s+1s
=> 5s
c) 8t+3r-7t-9r
=>8t-7t-9+3
=> t-6r
Hope it helps!
Answer:
3p , 5s , t - 6r
Step-by-step explanation:
(a)
4p + 2p - 3p ← add the first 2 terms
= 6p - 3p
= 3p
(b)
9s - 5s + 2s - s
= 4s + 2s - s
= 6s - s
= 5s
(c)
8t + 3r - 7t - 9r ← collect like terms
= (8t - 7t) + (3r - 9r)
= t - 6r

What is the value of arccos(sine (StartFraction pi Over 2 EndFraction))?
Answer:
0 radians or 2π radians
Step-by-step explanation:
arccos(sine (StartFraction pi Over 2 EndFraction)) is expressed as;
cos^(-1) (sin π/2)
Now, (sin π/2) in radians is same as (sin 180/2) = sin 90 in degrees.
Thus;
(sin π/2) = 1
Thus;
cos^(-1) 1 = 0
It could also be 360° in the fourth quadrant since cosine is positive there too.
Thus,
cos^(-1) (sin π/2) = 0° or 360°
In radians, this gives; 0 radians or 2π radians
0 radians or 2π radians is the value of arccos(sine (StartFraction pi Over 2 EndFraction)).
Here, we have,
given that,
The term is: arccos (sine (StartFraction pi Over 2 EndFraction)
so, we get,
arccos(sine (StartFraction pi Over 2 EndFraction)) is expressed as;
cos^(-1) (sin π/2)
Now, (sin π/2) in radians is same as (sin 180/2) = sin 90 in degrees.
Thus;
(sin π/2) = 1
Thus;
cos^(-1) 1 = 0
It could also be 360° in the fourth quadrant since cosine is positive there too.
Thus,
cos^(-1) (sin π/2) = 0° or 360°
In radians, this gives; 0 radians or 2π radians.

At 6 weeks old, Tarik's beagle puppy weighed 2.4 kg. Now, the 18-week old puppy welghs 8.4 kg. Find the rate of change.
Answer:
0.5 kg/week
Step-by-step explanation:
rate of change = (change in weight)/(change in time)
rate of change = (8.4 kg - 2.4 kg)/(18 weeks - 6 weeks)
rate of change = 6 kg / 12 weeks
rate of change = 0.5 kg/week

What is the correct value of z?
A. Z=12
B. Z=13
C. Z=10
D. Z=11
==========================================
Work Shown:
RS = RT
2z-15 = 9
2z = 9+15
2z = 24
z = 24/2
z = 12
The reason why RS is equal to RT in the first equation is because we have an isosceles triangle. Recall that any isosceles triangle has exactly two sides the same length, and the opposite base angles are congruent to one another. The congruent angles are indicated with the single arcs.
In short: the base angles S and T are congruent, so the opposite sides RS and RT are the same length. This leads to RS = RT.

james ran 25/100 of a mile yesterday and his friend Natasha ran 4/10 of a mile. who ran farther and how do u know
Answer: Natasha ran further
Step-by-step explanation:
1. Simplify both fractions into a common denominator:
25/100 and 40/100
2. Compare:
40/100 > 25/100
3. Answer:
Natsha ran further
Have a nice day! :D
Answer:
Natasha ran farther
Step-by-step explanation:
This is the answer because:
1) In problems like this, we have to find the common denominator and compare both of the fractions:
[tex]\frac{4}{10} = \frac{4 times10}{10 times 10} = \frac{40}{100}[/tex]
[tex]\frac{40}{100}[/tex] > [tex]\frac{25}{100}[/tex] = 40/100 is greater than 25/100.
Therefore, the answer is Natasha.
Hope this helps! :D
