Question

Shaniqua is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 inches. Shaniqua uses the equation to find b, the length of the triangle’s third side, in terms of s, the length of each of its two congruent sides. What is her equation written in terms of s?

Answer 1

The equation is:
2s+b=24
2s=24-b
s=12 - b/2
