If the length of a certain rectangle is decreased by 4cm and the width is increased by 3cm, a square with the same area would result. find the perimeter of original rectangle ​

The perimeter is 50

Step-by-step explanation:

The original area is LW

The new area is (L-4)(W+3)

These areas are the same

1:      (L-4)(W+3)=LW

You are also told that the new figure is a square, hence

2:     (L-4)=(W+3)

Equation (2) implies

3:     L=W+7

Substitute for L in Equation (1) and solve for W

(W+7-4)(W+3)=(W+7)W

W^2+3W+7W+21-4W-12=W^2+7W

6W+9=7W

W=9

Now use Equation (3) to solve for L

L=16

The perimeter is 2W+2L

P=18+32=50

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
