The perimeter of a rectangle is 524 m. The length is 42 m greater than the width. what is the length of the rectangle

1 answer:

6 0

Let the width be x

Width = x
Lenght = 42 + x

Perimeter of a rectangle = (2 x width) + (2 x lenght)
524 = (2x) + [2(42 + x)]
524 = 2x + 84 + 2x
440 = 4x
110 = x

Width = 110
Length = 42 + 110 = 152

Answer:

$5a^2+12b^2-40b$

Step-by-step explanation:

First distribute the -4 to the 2b and -3b. This leaves you with $5a^2-8b+12b(b+4)$

Now you can distribute the 12b to b and +4. This leaves you with $5a^2-8b+12b^2+48b$

Now you can combine your like terms leaving you with $5a^2+12b^2-40b$ .
