Answer:
x = ± 2
Step-by-step explanation:
Given
3x² = 12 ( divide both sides by 3 )
x² = 4 ( take the square root of both sides )
x = ±
= ± 2
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 10
B 1 since you would round 1.9 to 2 and 0.7 to 1
I think the answer is c= 0.248
