Answer:

O  A. (-1,2)

Step-by-step explanation:

y=x+3

2=-1+3

2=2

y=-x+1

The length of a rectangle is a inches. Its width is 5 inches less then the length. Find the area and perimeter of the rectangle
Travka [436]

Answer:

Area = (a² -5a) in²

Perimeter = (4a -10) in

Step-by-step explanation:

Let the length of the rectangle be a.

Given that, its width is 5 in less than the length.

So,

length ⇒ a

width ⇒ (a - 5)

First, let's find the area of the rectangle.

Area = length × width

Area = a ( a - 5 )

<em>Solve the brackets.</em>

Area = <u>(a² -5a) in²</u>

<u />

Now, let us find the perimeter of the rectangle.

Perimeter = 2 ( l + w )

Perimeter = 2 ( a + a - 5 )

Perimeter = 2 ( 2a - 5 )

Perimeter = <u>(4a -10) in</u>
