I am gonna guess it is C. Both for this one.
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
<u>Answer-</u>
<em>The value of x can be anything </em><em>between 0 to 15</em>
<u>Solution-</u>
Perimeter of a geometrical figure is the sum of lengths of all its sides.
So, the value of the perimeter of the given pentagon would be,

As given in the question that, the perimeter is less than or equal to 51 meters.
So,


As the side length can not be negative, so x must be positive, i.e

Answer:
3x - 11
Step-by-step explanation:
x + 5/ 3x-11
3x - 11 is the quotient
The correct answer is b. When raising a number to a negative power switches the denominator and the numerator.
