I believe the answer would be A. 729 because 9 • -9 = -81 • -9 = 729. (A positive times a negative equals a negative, and a negative times a negative is a positive.)

The answer is A because 9 x 9 x 9 = 729. The exponent above the 9 means to multiply the base (9) 3 times.

What is the value of x in the equation 3/2 (4X - 1) - 3x = 5/4 - (x +2)

Leokris [45]

Step-by-step explanation:

3/2(4x-1)-3x = 5/4-(x+2)

6x -3/2 -3x = 5/4 -x -2

3x -3/2 = 5/4-2-x

4x=5/4 -2 +3/2

4x= (5-8+6)/4

4x=3/4

x=3/16
