A rectangle has a length of 2x+7 and a width of 3x+8 . Write and simplify an expression for the perimeter of that rectangle.

A rectangle has four sides so we double each side and add them to each other:

2(2x+7)+2(3x+8y)

=4x+14+6x+16y

=10x+16y+14

Step-by-step explanation:

2(2x+7)+2(3x+8y)

=4x+14+6x+16y

=10x+16y+14

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
