Answer 1

a) x^2+8x+16

Answer 2

Well A and B are the same, so i have to go with A and B! I'm real good at math, even though this was easy!!

Answer 3

FOIL

(x+4)(x+4)

Answer 5

a

Answer 6

x + 4

x + 4

--------

x²+4x+4x+16

x² + 8x + 16

Multiply the 4s to get 16 and write +16.

Multiply the top x and the 2nd 4 to get +4x and write it down.

Multiply the 2nd x and the top 4 to get +4x and write it down too.

Multiply the x's together to get x² and write it down. Combine like terms, here only the two 4x's, and you get x² + 8x + 16.

Answer 7

the answers A

Answer 8

c.) x^2+16

Answer 9

(x+4)^2

(x+4)(x+4)

x^2+4x+4x+16

x^2+8x+16

Answer 10

x*4=4x

4*4=16

Answer 12

the answer is the (a)

Answer 13

(X+4)^2= (X+4)(X+4)= X(X+4)+4(x+4)

X^2+4X+4X+16=

X^2+8X+16
