Question

The sides of a triangle are represented by the expressions 5-4x², 32x - 5x², and

x² - 5. What is the perimeter of the triangle?
A-8x² + 32x
B 2x² + 32x
C-8x² + 32x + 10
D 2x¹ + 32x + 10

Answer 1

−8x² + 32x

Explanation:

The sides of a triangle are represented by the expressions 5-4x², 32x - 5x², and x² - 5.

What is the perimeter of the triangle?

A-8x² + 32x

B 2x² + 32x

C-8x² + 32x + 10

D 2x¹ + 32x + 10

Perimeter = sum of the sides

5 - 4x² + 32x - 5x² + x² - 5 =

-4x² + 32x - 5x² + x² =

-9x² + 32x + x² =

-8x²+32x
