You have to input the 5 into the x place. so it would be y=3(5) and you get the answer y=15
You just do 12•.65. Then that’s your answer.
The simplified expression that represents the total perimeter of the triangle is 2x^2 + 10x + 3
<h3>How to determine the perimeter?</h3>
The side lengths are given as:
2x^2 + 5x + 3, 2 + 2x and 3x - 2
Add these lengths to determine the perimeter (P)
P = 2x^2 + 5x + 3 + 2 + 2x + 3x - 2
Collect like terms
P = 2x^2 + 5x + 2x + 3x + 3 + 2 - 2
Evaluate the like terms
P = 2x^2 + 10x + 3
Hence, the simplified expression that represents the total perimeter of the triangle is 2x^2 + 10x + 3
