Question

write the following as an algebraic expression. then simplify. the perimeter of the isosceles triangle with base length x - 8 and legs of length x. the answer is (simplify your answer)

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a triangle is the sum of the lengths of its sides. For an isosceles - triangle with two legs of length $x$ and a base of length $x - 8$, the expression for the perimeter is $P=x + x+(x - 8)$.

Step2: Combine like - terms

$P=(x + x+x)-8$.
Combining the $x$ terms, we have $x + x+x = 3x$. So, $P = 3x-8$.

Answer:

$3x - 8$
