Answer:

step 2

Step-by-step explanation:

(-6)^2 ≠ 36^2

(-6)^2 = 36

Step 2: She did not simplify under the square root correctly

under the square root:

(-6)^2 =36

and -4(5)(-8) =160

therefore under the square root it needs to be square root of 36+160 which is square root of 196.

That answer is 14 when square rooted

x = 120

Too long to exaplin.

Just trust me

N= 100+n(10)

1 5/6
