Answer:

x = - 10, x = 6

Step-by-step explanation:

Given

(x + 2)² = 64 ( take the square root of both sides )

x + 2 = ± \sqrt{64} = ± 8 ( subtract 2 from both sides )

x = - 2 ± 8

Thus

x = - 2 - 8 = - 10

x = - 2 + 8 = 6

Describe the symmetry of these functions
Oduvanchick [21]
If it was line symmetry it would need to repeat the same shape twice, which the first follows but the second doesn’t.
if it was rotational, you would need to be able to take the shape in the top right and rotate it counterclockwise or clockwise to get the shape that locks in place. that doesn’t follow that.
both line and rotational symmetry is incorrect because the first example would need to lock up inside the right side of that example.

the answer is C
