Answer:

C

Step-by-step explanation:

x + 2y = 21

4x + y = 21

Multiply the second equation by -2 to get:

 -8x - 2y= -42  {Add this to the original equation; y's will be eliminated}

+  x + 2y = 21

-7x = -21

A rectangle hasan area of 100 square yards and a perimeter of 58 yds. What is the length of the longer side of the rectangle?
Vinil7 [7]

Answer:

The longer side of the rectangle is 25 yards.

Step-by-step explanation:

The area of a rectangle, A = 100 square yards

The perimeter of a rectangle, P = 58 yards

We formula for area and perimeter of a rectangle is given by :

A = lb

and

P = 2(l+b)

ATQ,

lb = 100 ...(1)

2(l+b) = 58

(l+b) = 29 ....(2)

We need to solve equation (1) and (2).

l = 4, b = 25

So, the longer side of the rectangle is 25 yards.
