Your answer would be (60x + 240)/(8x² + 32x).
When multiplying fractions, you are able to just multiply the numbers across like you do usually, which gives us the expression 5(12)(x + 4) as the numerator, and 4(x)(2x + 8) as the denominator. Then all we need to do is expand and simplify:
5 × 12 = 60
60(x + 4)
= 60x + 240
4 × x = 4x
4x(2x + 8)
= 8x² + 32x
So your final expression is (60x + 240)/(8x² + 32x).
I hope this helps!
