Step-by-step explanation:
Perimeter of a rectangle= 2(l+b)
= 2( 4m-1+3m+2)
=2(7m+1)
= 14m+2
Answer:
The value of the expression is 80.
14 - 6 = 8.
10 x 8 = 80.
14x + 23
The lengths of three sides of a triangle are 5x + 9 feet, 2x + 14 feet, and 7x feet.
The perimeter of a triangle: the sum of all of its sides.
5x + 9 + 2x + 14 + 7x
It's the expression of the perimeter of the triangle. Once you will be asked to find x, you'll probably be given the exact perimeter of the triangle.
