Raymond wants to plow a garden that is 5 feet longer than it is wide and has a total perimeter of 170 feet. what are the dimensions of his new garden

If the Length is 5 feet longer than the width then we can say the width is X and the length is X+5. If the perimeter is 170 feet then we can calculate the perimeter as
X+(X+5)+X+(X+5)=170 feet
2X+2 (X+5)=170 feet
2X+2X+10=170 feet
4X+10=170 feet
4X=170 - 10 feet
4X=160
X=160/4
X=40
so the width of the garden is 40 feet and the length is 40+5=45 feet

Isolate the variable by dividing each side by factors that don't contain the variable.

a = 4 √69m^3/m

That 3 is on top of the m
