Solve the following equation for x. 7x^2– 112 = 0
O A
X=-4, X=-4
O B.
X= 4, x= 4
O c.
X= -4, X= 4.
OD.
x = 5, x= -5

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
