Arectangle’s length is 2 units more than twice its width. its area is 40 square units. the equation w(2w + 2) = 40 can be used to find w, the width of the rectangle.

what is the width of the rectangle?

4 units
5 units
10 units
12 units

Option 1 is correct that is 4 units

Explanation:

Given equation is w(2w+2) = 40

we can simplify the equation by opening the brackets on left hand side of the equation we get + 2w =40

taking 2 as common factor from both the sides we will get

+ w=20

after middle term split we will get

+ 5w-4w -20=0

after simplification we will get (w+5)(w-4)

we will two values w= -5 , 4

-5 will be neglected because width can not be negative

Hence, width is 4 units.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
