A rectangle has a length 6 more than its width. If the width is decreased by 2 and the length
Secreased by 4, the resulting rectangle has an area of 21 square units. What is the length of the
original rectangle? What is ratio of the original rectangle's area to the new rectangle's area?
What is the perimeter of the new rectangle?

The original length is 11.

The original width is 5.

Ratio is 21:55

Perimeter of the new triangle (the 7x3 one, not original) is 20.

Step-by-step explanation:

7*3=21

7+4=11

3+2=5

11*5=55

7+7+3+3=20

b if for most of the graph

d if y intercept

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
