l=20
Step-by-step explanation:
The area can be found using the following equation:
Given the information provided, we are also told the following:
Therefore, we can plug in our length and our area:
We can solve by using the quadratic formula.
w=12, so w+8=20.
Answer:
Let us consider the expression:
(1)
Now, the quotient of power rules says that the numbers that have same base can be find by subtracting if powers are with same sign
And adding if powers are with opposite sign.
We will solve equation (1) by this quotient of power rule.
So, it can be rewritten as:
.
