You will need 90 feet of fencing to put all the way around a rectangular garden. the width of the garden is 10 feet. what is the length?

if it is a rectangle then the sides of the width would be the same. Also with the sides of the length. So add the widths, 10+10=20. Subtract 20 from 90, 90-20=70. Divide 70 by 2, 70÷2=35.

The length would be 35 feet.

A drawing shows a rectangular plot of dirt with 10 plants in 2 rows inside it. The top side is labeled question mark feet. The right side is labeled 10 feet. Below, text says perimeter = 90 feet.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
