Question

Write an inequality for x that would give this isosceles triangle and perimeter of at least 137 ft. 4x+3 2x+7

Answer 1

The inequality is
`8x+17\geq 137`

Explanation:

Given : The isosceles triangle with base and side 4x+3, 2x+7.

And the perimeter is at least 137ft.

To write : An inequality for x

Solution : Let the base
`b=4x+3` and sides
`s=2x+7`

The perimeter of Isosceles triangle is
`P=2s+b`

where s=side and b=base

Now, we have given that perimeter is at least 137 ft.

Therefore, the inequality form is

`2(2x+7)+(4x+3)\geq 137`

`4x+14+4x+3\geq 137`

`8x+17\geq 137`
