If f(x) = x2 - 2x), which expression is equivalent to 10?
O-2+I
O-2-I
2+I
2-I

step-by-step explanation:

the square root of 16 is 4.

4*4 = 16

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
