Answer:
Step-by-step explanation:
Area = length * width
length: x + 3
width: x - 5
A = (x + 3)(x - 5)
Simplify (x + 3)(x - 5) using the FOIL method:
1. First numbers: multiply the first number of each binomial together--x*x = x%5E2
2. Outer numbers: multiply the outer number of each binomial (out of the entire expression, the number farthest to the left (x) and the number farthest to the right (-5))--x*-5 = -5x
3. Inner numbers: multiply the inner number of each binomial--3*x = 3x
4. Last numbers: multiply the last number of each binomial--3*-5 = -15
==> Now, add all of the results together and combine like terms: x%5E2+-+5x+%2B+3x+-+15 = x%5E2+-+2x+-+15
Therefore, A = x%5E2+-+2x+-+15
Answer:
I think it's 9:50
Step-by-step explanation:
To solve the negative exponents , we have to apply the negative exponent rule or the fractional exponent rule.
<h3>How are
negative exponent calculated?</h3>
To calculate the negative exponent we need to remember about the negative exponent that the base is on the opposite side of the fraction. Here , We need to flip the fraction so that the base will be on the other side.
Negative exponent Rule :-
Now , we will solve a fraction with negative exponent
For example ; Simplify the fraction 
Solution : 
= 9
Here, 9 is the answer of the above example.

Answer:
It is the letter A
Step-by-step explanation:
To find the perimeter you need to add all the sides. Since the width of the rectangle is 2 feet, you need to add it to another 2 since they have two equal sides. DO the same with 18 inches which is the length.
