Factor x2 + 16x + 64 by using the perfect squares method

(x+8)^2

Step-by-step explanation:

x2 + 16x +64

(x+8)(x+8)

(x+8)^2

(x +8) (x +8)

Step-by-step explanation:

x^2 + 16x + 64

8*2=16

And 8*8 =64

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
