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:
B. -3.25
Step-by-step explanation:
Multiplying by 0.5 is the same as divided by 2.
*Dont forget the negative.
-0.5(6.5)= 6.5/-2 = -3.25
Carey earns c hourly
Anderson earns $6 hourly which is also 1+ c/2
So, 6=1+c/2
12=2+c
c=$10
Carey earns $10 hourly
Area of a square = L * L
As you know 17 * 17 = 289
So length of one side of square equals 17
Let
x---------> the length of the sides that have the same length in meters
we know that
the perimeter of the figure is equal to
<u>solve for x</u>
therefore
<u>the answer is</u>
Each of the same length side is 
long
