Answer:
24
Step-by-step explanation:
3(2n-8)=5n distribute 3
6n-24=5n combine like terms
-24=-n divide by -1 on both sides
24=n
n=24
They aren't equivalent
<h2>Explanation:</h2>
In order to determine whether the expression:

is equivalent to:

Genevieve needs to follow these steps:
Step 1. Get rid parentheses

Step 2. Combine like terms

Step 3. Solve

Answer:
Area= 64pi or 201.06
Circumference: 16pi or 50.265
Step-by-step explanation:
Area= \pi r^{2}
pi (8)^2 = 64pi or 201.06
Circumference= 2pir , 2(pi)8 = 16pi or 50.2
Answer:

Step-by-step explanation:
Width=(Length-2) units
W=(L-2) units
Area of the rectangle= 35 square units
Area = length* Width

Subtracting 35 both sides:

Solving the quadratic equation for 'L' ;
Using factorization:

Taking common from the equation :

OR

The length cannot be negative, therefore Length(L)= 7
