Answer:
2x² + 19x + 45
Step-by-step explanation:
(x + 5)(x + 1) + (x + 5)(x + 8) ← expand both sets of factors using FOIL
= x² + 6x + 5 + x² + 13x + 40 ← collect like terms
= 2x² + 19x + 45
Answer:
14800
Step-by-step explanation:
Area of trapezoid = 
Using the formula above, our equation will look like this:

so put the rate on 1 side, and all the given numbers in other side
the rule will be like this:
R=I/PT
R=4320/6000×9
R=6.48%
