Answer:
48 in^2
Step-by-step explanation:
If the quadrilateral is actually 4" wide and 12" long, then the area is 48 in^2.
no because 7.909090 is greater than 7.9 so it would not make that a true statement.
Problem 1) We need exactly one unit tile (the smallest square tile) to fill up the empty space to make a completed rectangle. In this case it would be (x+2)^2 = x^2+4x+4
Problem 2) The answer here is choice B since (x+3)^2 expands out to x^2+6x+9. Tacking on a "-6" will take the +9 down to +3. In other words, x^2+6x+9-6 = x^2+6x+3
Lets get started :)

We have the same base, which in this case is x.
When multiplication occurs in the same base, we add the powers
↓ (I am going to perform the problem separately and then give the final answer as the power to x)
=
↓
x²
The power of a power should be performed by multiplying the powers together.
2 x
=
Your final answer will be the second option
Answer: around 22 (21.99)
Step-by-step explanation:
SInce the diameter of a circle is 2piR, you just need to multiply the radius (half of the diameter ,3.5) by pi and then 2. The answer is around 22
