Question

A rectangle has length 3x + 4 and width 2x - 1. What is the perimeter of the rectangle?

Responses
A 10x + 610x + 6
B 10x + 1010x + 10
C 5x + 35x + 3
D 6x² + 5x - 4

Answer 1

I believe the answer is 10x + 6

Explanation:

well we know that the same length and width of a rectangle is twice . this means that you can multiply the length and width by 2 to get the perimeter and add them . so by foiling you will have 2(3x+4) + 2(2x-1). you can solve this and simplify it to get 6x + 8 + 4x - 2 . simplify this more to get 10x + 6.

I'm a little confused because I do not see an answer on your question that says 10x + 6 . can you add a diagram, formatting, or more context if I am wrong?
