What's this equation in vertex form? !
i really need . you. [20 points]

y=8(x^2 + 4x + 4) +17 + -32

Simplify:

y = 8(x^2 + 4x + 4) + 15

Use distributive property:

y = 8x^2 + 32x +32 - 15

Simplify:

y = 8x^2 + 32x +17

Complete the square using  form ax^2+bx+c:

a = 8, b = 32, c = 17

vertex form = a(x+d)^2+e

d = b/2a and e = c-b^2/4a

d = 32/2*8 = 32/16 = 2

e = 17 - 32^2/4*8 = 17-1024/32 = 17-32 = -15

Vertex form = y = 8(x+2)^2 + -15

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
