Answer:

$\Huge \boxed{\mathrm{-7}}$

$\rule[225]{225}{2}$

Step-by-step explanation:

Let the number be x.

$4(x+8)=4$

Dividing both sides by 4,

$x+8=1$

Subtracting 8 from both sides,

$x=-7$

The number is -7.

$\rule[225]{225}{2}$

Do 10 to the sixth power first then multiply that by 7 you use PEMDAS

I guess it's b

${x}^{2} + 8x + 16 \\ \\ 1. \: {x}^{2} + 2(x)(4) + {4}^{2} \\ 2. \: (x + 4)^{2}$
