Answer:

15w - 15y - 36

Step-by-step explanation:

Combine like terms

In this case the only two terms would be numbers without variable and numbers with the variable w

First lets combine the numbers with no variable which are -16 and -20. you subtract these two -16 - 20 = -36 and get -36

Now lets combine like terms for w, it doesn't matter which order you go in exactly but in the case I will do

1. combine 8w and 7w, since these are both positive you will add the together

8w + 7w = 15w

2. Now combine -11y and -4y, since these are both negative you will subtract them and get -15y

What are the factors in the expression 4x(3x^2+5y)?
Bess [88]

4x(3x²+5y) expand by distributing terms

4x*3x²+4x*5y take out the constants

(4*3)xx²+4x*5y simplify 4*3 to 12

12xx²+4x*5y use product rule=xᵃxᵇ=xᵃ+ᵇ, and change the two variables (the x's) into ones, because if there is just one variable with no number by it, then it is a one.

12x¹⁺²+4x*5y and simplify 1+2 to 3.

12x³+4x*5y finally simplify 4x*5y to 20xy

12x³+20xy

Hope this helps, now you know the answer and how to do it. Stay healthy and safe and HAVE A BLESSED AND WONDERFUL DAY! :-)

What is the vertex form, f(x) = a(x - h)2-k, for a parabola that passes through the point (2,8) and has (1,0) as its
Novay_Z [31]

Answer:

Step-by-step explanation:

hello :

f(x) = a(x - h)²-k   ....vertex form  when the vertex is : (h,k)

h=1  and  k=0   so : f(x) = a(x-1)²

a parabola that passes through the point (2,8) : f(2)=8

a(2-1)² =8

a= 8

f(x) = 8(x-1)²=  8(x²-2x+1)

f(x) 8x²-16x+8   .....standard form
