Which value for x makes the open sentence true? 8 + 3 • x = 2 squared + x squared question 1 options: 5 4 3 2

8 + 3 *X = 2^2 + X^2

Simplify:

8 + 3x = 4 +x^2

Subtract x^2 from each side:

8 + 3x - x^2 = 4

subtract 4 from each side:

8 + 3x -x^2 -4 = 0

Simplify:

3x - x^2 +4 = 0

Factor

-(x-4)(x+1) =0

X = 4, -1

The answer would be 4.

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

the answer should be a. snail
