Answer:
<h2>A = 82.5 in²</h2>
Step-by-step explanation:
The formula of an area of a trapezoid:

b₁, b₂ - bases
h - height
We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:

Answer:
B. -3 1/2y + 2
Step-by-step explanation:
Our expression is:
.
Let's first distribute out that parentheses. Remember that distribution is simply taking the sum of the product of the outside term with each of the inside terms. Here, the outside term is 1/2 and the inside terms are 4 and -2y:

Now, we have:

We want to combine like terms, which means combining all the terms with y in them:

Remember that -7/2 can be written as the mixed number -3 1/2, so our final answer is:
-3 1/2y + 2
The answer is thus B.

Given : 
To Find : What are the factors of 
Solution:

Since 100 =

using property : 

Thus the factors of

Part 2

The answers is A.
Part 3

The answers is
B.
Part 4
The pattern in this sequence is:

Let's list first six terms:

This is a infinite sequence. The patern is obvious and we could find any term within the sequence.
