The length of a rectangle is (x+5) and the width is (x+2). the area of the rectangle is 70 square feet. what is the length of the rectangle?

The length of the rectangle is 30 feet.

Step-by-step explanation:

Because the equation for area is length times width, you would have to set the two equations to seventy and multiply them.

    (x+5) (x+2) = 70

    2x + 10 = 70

Then, you would have to subtract ten from both sides, cancelling it from the left side.

    2x = 60

Then do the opposite and divide sixty by two, therefore getting a length of thirty feet.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
