Which represents the solution(s) of the equation x2 = 64?

1 Take the square root of both sides.

x=±√64

2 Since 8×8=64, the square root of 64 is 8

x= ±8

so your answer is ±8 I hope it helps

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
