Answer:
x = ±sqrt(5/2)
Step-by-step explanation:
6x^2−2=13
Add 2 to each side
6x^2−2+2=13+2
6x^2 = 15
Divide each side by 6
6/6x^2 = 15/6
x^2 = 5/2
Take the square root of each side
sqrt(x^2) = ±sqrt(5/2)
x = ±sqrt(5/2)
76/2=38 so half her mothers age is 38. And since Moira is 3 less than the half of her mothers age, Moira is: 38-3=35
