Question

What is the perimeter of the image attached?? (PLEASE HELP I WILL MARK BRAINLIEST)

Answer 1

Answer:

$Perimeter = 3x + 3$

Step-by-step explanation:

Perimeter of the given triangle in the figure is the sum of all three sides.

The expressions for the 3 sides are given as, $x, (x - 3), (x + 6)$.

Therefore,

$Perimeter = x + (x - 3) + (x + 6)$

Simplify,

$Perimeter = x + x - 3 + x + 6$

Collect like terms

$Perimeter = x + x + x - 3 + 6$

$Perimeter = 3x + 3$
