Answer:
B) 15
Step-by-step explanation:
sqrt(6x) = 3 sqrt(10)
Square each side
(sqrt(6x))^2 = (3 sqrt(10))^2
Remember (ab)^2 = a^2 b^2
6x = (3^2) sqrt(10))^2
6x = 9 * 10
6x = 90
Divide each side by 6
6x/6 = 90/6
x = 15
Answer:
C
Step-by-step explanation:
In the attached file
3x⁶y² + 57x⁵y³ + 252x⁴y⁴
= 3x⁴y²(x² + 19xy + 84y²)
= 3x⁴y²(x² + 12xy + 7xy + 84y²)
= 3x⁴y²(x(x + 12y) + 7y(x + 12y))
= 3x⁴y²(x + 12y)(x + 7y)
