The area of a rectangle is 135 square feet. The width is 6 feet less than the length. Find the dimensions of the rectangle
drek231 [11]

The length is 15 inches and width is 9 inches

Step-by-step explanation:

Let

l be the length

and

w be the width

w = l-6

The area of rectangle is 135 ft^2

The formula for area is:

Area=l*w\\135=l*(l-6)\\135=l^2-6l\\l^2-6l-135=0\\l^2+9l-15l-135=0\\l(l+9)-15(l+9)=0\\(l+9)(l-15)=0\\l+9 = 0 => l=-9\\l-15 = 0 => l=15\\

As the length cannot be negative, so we will use the value of length 15

If length 15,

w=l-6

w=15-6

w=9

So,

The length is 15 inches and width is 9 inches

Jillian is trying to save water, so she reduces the size of her square grass lawn by 8 feet on each side. The area of the smalle
dsp73
<span>The answer is 20 feet by 20 feet. Let's solve the equation: (x – 8)^2 = 144. (x - 8)^2 = 12^2. Since a^2 = b^2 is the same as a = b, then (x - 8)^2 = 12^2 can be simplified to: x - 8 = 12. Now, solve for x. x = 8 + 12. x = 20. Therefore, the dimensions of the original lawn were 20 feet by 20 feet.</span>

Find the measure of the three missing angles in the rhombus below.<br>Explain it.
wlad13 [49]

The measure of the three missing angles in the given rhombus are:

x = 122°

z = 58°

y = 122°

<h3>What is a Rhombus?</h3>

A rhombus is a quadrilateral with four interior angles. In a rhombus, the opposite angles are congruent while the adjacent angles are supplementary to each other.

x and 58° are adjacent angles and are therefore supplementary.

x = 180 - 58 = 122°

z = 58° (opposite angles)

y = x = 122° (opposite angles)
