Simplify (-2x)^4
a.) -16x^4
b.) -8x^4
c.) -2x^4
d.) 8x^4
e.) 16x^4

answer

c.)

Step-by-step explanation:

(-2x)^4 = -2x^4

which is the same as answer c.)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
