Answer:
66.67
Step-by-step explanation:
20-12=8
8/12=0.6666667
0.6666667x100=66.67
Move the -7 to the right, its sign will flip (do you know why?)
Negate both sides to change -x to x
-x = 16+7
-x = 23
x = -23
You need 12 square roots of 1764 ?
Why not find the square root of 1764 first (it's 42) and then take 12 of those ?
