Answer:
F. x(y +12)
Step-by-step explanation:
The factor of 1/5 can be distributed, while the factor of x is left alone.
15/x(5y +60) = x(1/5(5y +60)) = x(y +12) . . . . matches F
Answer:
x² + 4x + 20 = 12x - 5
x² + 4x - 12x + 20 + 5 = 0
x² - 8x + 25 = 0
Δ = √b² - 4ac
= √(-8)² - 4×1×25
= √64-100
= √(-36)
x ∉ R
I think it’s 2 5/9. You might want someone to double check it, though.
