3x/5.. because when the bracket opens then the -7 and +7 get cancelled..
Answer:
yes because if you put a vertical line on it it only goes threw it once it is also called the <u>vertical line test</u>.
7 devide by k in algebric function = 7/k
2w + 2l = 25
2 * 2 + 2l = 25
<em><u>Simplfiy.</u></em>
4 + 2l = 25
<em><u>Subtract 4 from both sides.</u></em>
2l = 21
<em><u>Divide both sides by 2.</u></em>
l = 10.5
Now that we have the value of l, we can find the area.
A = lw
A = 10.5 * 2
A = 21.
The length is 10.5cm.
The area of the rectangle is 21cm^2
