Let the width of the rectangle be x
then the length is x+2
we are given the area as 80 square meter
and we know the area of a rectangle is given by
area=L*W
area=(x+2)*x
but our area=80
80=(x+2)*x
x^2+2x=80
x^2+2x-80=0
we use the quadratic formula to solve this which gives us
x=8
therefore our width is 8
and our length is 10
Answer:
y = 3x + 1
Step-by-step explanation:
y = 3x + b
-5 = 3(-2) + b
-5 = -6 + b
1 = b
<h3><u>The value of y is equal to 1.</u></h3>
7(y - 3) = 2(y - 9) + 2y
Distributive property.
7y - 21 = 2y - 18 + 2y
Combine like terms.
7y - 21 = 4y - 18
Subtract 4y from both sides.
3y - 21 = -18
Add 21 to both sides.
3y = 3
Divide both sides by 3.
y = 1
2.0076* 10^4
move the decimal 4 places to the right
20076.
20076 < 26970
