Answer:
[tex]3(5n - 2) \times (2n - 5)[/tex]
Step-by-step explanation:
[tex]30 {n}^{2} - 87n + 30[/tex]
[tex]3(10 {n}^{2} - 29n + 10)[/tex]
[tex]3(10 {n}^{2} - 4n - 25n + 10)[/tex]
[tex]3(10 {n}^{2} \times (5n - 2) - 25n + 10)[/tex]
[tex]3(2n \times (5n - 2) - 5(5n - 2))[/tex]

if the sum p(x)=ax^2-3x+b and q(x)=3x^3-12x^2+cx-13 is r(x)=3x^3-8x^2+3x-5,then find the value of a,b and c.
Answer:
a=4, b=8, c=6
Step-by-step explanation:
ATQ, p(x) + q(x) = r(x)
3x^3-(12-a)x^2-(3-c)x+b-13 = 3x^3-8x^2+3x-5
Comparing the coefficients, we have
12-a=8, a=4
b-13=-5, b=8
-(3-c)=3, c=6

Step-by-step explanation:
A population of bacteria contains 150 bacteria in generation 1 and triples in
population every generation. This sequence represents the number of
bacteria for the first few generations:
150, 450,1350, ...
What is the explicit formula for the number of bacteria in generation n?
Answer: bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)
Step-by-step explanation:
It looks like geometrical sequence, each next generation is three times greater than previous one. So the r of this sequence is 3.
The first generation has 150 representatives, so b1=150
The formula of geometrical sequence is bn=b1*r^(n-1)
(in our case bn is a quantity of bacteria in generation n)
so bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)

The formula for the perimeter of a rectangle is P = 2l + 2w. Solve the formula for l
in terms of P and w.
Answer:
P/2 -w = l
Step-by-step explanation:
P = 2l + 2w
Subtract 2w from each side
P-2w = 2l + 2w-2w
P -2w = 2l
Divide each side by 2
(P-2w)/2 = 2l/2
P/2 -w = l

how do i do this?
Answer:
[tex] \frac{5}{8} k = 25 \\ \frac{5k}{8} = 25 \\ 5k = 25 \times 8 \\ 5k = 200 \\ k = \frac{200}{5} \\ k = 40[/tex]
I hope it helped U
stay safe stay happy
Answer:
k=1/40
Step-by-step explanation:
multiple both sides by 8k
5= 25×8k
simplify 25×8k to 200k
5=200k
divide both sides by 200
5/200=k
simplify 5/200 to 1/40
1/40= k
switch sides
k=1/40
What is the slope of –3x + 5y = 10? A. m = B. m = 5 C. m = – D. m = –3
Answer:
The slope is 3/5
Step-by-step explanation:
–3x + 5y = 10
Rewrite the equation in slope intercept form y = mx+b where m is the slope and b is the y intercept
Add 3x to each side
5y = 3x+10
Divide by 5
y = 3/5 x + 10/2
The slope is 3/5

Step-by-step explanation:
Since we already have the values of the variables and the equation, all we have to do is plug in the numbers.
-b + 3x
-(4) + 3(-5)

-19
Answer:
[tex]\boxed {\boxed {\sf -19}}[/tex]
Step-by-step explanation:
We are asked to evaluate the following expression.
[tex]-b+3x[/tex]
We know the b is equal to 4, and x is equal to -5.
b=4 x=-5We can substitute the values into the expression.
[tex]-(4) + 3(-5)[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Multiply first. We multiply -1 and 4, then 3 and -5.
[tex][-1 *4] + 3(-5)[/tex]
[tex]-4+ [3*(-5)][/tex]
[tex]-4+-15[/tex]
Add.

Martha has a French cookie recipe that calls for baking the cookies for 14 to 18 minutes at 180∘C. Her oven measures temperature in Fahrenheit only. At what temperature in degrees Fahrenheit should she set her oven to make the cookies per the recipe?
Answer:
180° Celsius is equal to approximately 356° Fahrenheit
Step-by-step explanation:
I hope this helps.
The value of 180 degree Celcius in Fahrenheit is 356.
What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Martha has a French cookie recipe that calls for baking the cookies for 14 to 18 minutes at 180∘C.
The temperature in Fahrenheit will be calculated as,
F = 1.8C + 32
F = ( 1.8 x 180 ) +32
F = 356
Therefore, the value of 180 degree Celcius in Fahrenheit is 356.

You eat 3/10 of a coconut. Your friend eats 1/5 of the coconut. What fraction of the coconut do you and your friend eat? Write your answer as a fraction in simplest form
Answer:
1/2 of the coconut.
Step-by-step explanation:
1/5 is equal to 2/10, so we can add these two fractions as 3/10 + 2/10, or 5/10. Simplifying this gets us 1/2, so you and your friend eat, in total, half of the coconut.

Find the equation for the
following parabola.
Vertex (0, 0)
Focus (2, 0)
A. 2x2 = y
B. y2 = 8x2
C. x2 = 8y
D. y2 = 8x
If the vertex of the parabola is (0, 0) and the focus is (2, 0). Then the equation of the parabola is x² = 8y. Then the correct option is C.
What is the parabola?It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
The vertex of the parabola is (0, 0) and the focus is (2, 0).
Then the equation of the parabola passing through the origin is given as
x² = 4ay
Then the value a is equal to 2.
Then the equation will be
x² = 4 × 2 × y
x² = 8y
