(15 PNTS!!) The area of a rectangle is 168 square meters. If the length of the rectangle is 2 m longer than it’s width, find the dimensions. Let w be the width of the rectangle in meters and solving for w.

12m

Step-by-step explanation:

To find the area of the rectangle we multiply l by w

so

lw=a

if l=2+w we can substitute l with 2+w

so now

w(w+2)=168

distribute

w^2+2w=168

Now we use guess and check to solve

13^2 is 169

so 12^2 is 144 and 2*12=24

and 144+24=168

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
