Answer:
4u^2 + 16u + 15
Step-by-step explanation:
Multiply each of the terms in the first binomial by each of the terms of the second binomial (4 multiplications in all).
(2u + 3)(2u + 5) = (2u)(2u + 5) + 3(2u + 5)
= (2u)(2u) + (2u)(5) + 3(2u) + 3(5)
= 4u^2 + 10u + 6u + 15
= 4u^2 + 16u + 15
A force of 182.6 lb should be applied to lift 700 lb object.
<h3>How to calculate the force?</h3>
Let the force required to lift be F
Total length = 29 in.
Distance of short end from pivot = in.
Distance from long end = 29-6 = 23 in.
Now Equating moments
F × 23 = 700x6
23F = 4200
F = 4200/23
= 182.6 lb
A force of 182.6 lb should be applied to lift 700 lb object.

So you need to make out the lengths for the triangle. For the height, you can subtract the short length (100) from the longer length (1250) to get the height of the triangle. The base is the length at the very top, 75. So right now you have 150 for height and 75 for the base. Now use the formula to get 75 root 5.
