Answer:
The expression to find the perimeter is [tex]12x^2-6[/tex].
Step-by-step explanation:
Given: The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.
To find: The expression that can be used to find the perimeter of the triangle.
Solution:
We have,
The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.
We know that,
The perimeter of a triangle is sum of all the sides.
So, Perimeter [tex]=(4x^2-3)+(4x^2-2)+(4x^2-1)[/tex]
[tex]\implies \text{Perimeter}=12x^2-6[/tex]
Hence, the expression to find the perimeter is [tex]12x^2-6[/tex].
