Answer:244.8
Step-by-step explanation:
15% of y=36.72
15/100 x y=36.72
15y/100=36.72
Cross multiply
15y=36.72 x100
15y=3672
Divide both sides by 15
15y/15=3672/15
y=244.8
We have the following expression:
(2x + 5) * (7-4x)
Rewriting we have:
14x - 8x ^ 2 + 35 - 20x
Grouping terms with the same exponent:
-8x ^ 2 + x (14-20) + 35
Rewriting:
-8x ^ 2 - 6x + 35
Answer:
the quadratic expression for this is:
-8x ^ 2 - 6x + 35
