Angelique wants to have a rug that is 9 feet long, 7 feet wide. the rug will cover the whole floor except a border that is x feet wide.the area of her room is 167 sq ft. find x

Answers

Answer 1

The width of the border will be about 2.5 feet.

The area of the rug is 9 by 7. Let's call the width of the border x. Therefore, the length of the rug will switch to 9 + 2x. The border is on both sides of it, so we add on 2x. Then, the width is 7 + 2x.

The area of the room is therefore: (9 + 2x)(7+ 2x).

We know the area of the room, so we can write and solve the following equation.

(9 + 2x)(7 + 2x) = 167
4x^2 + 32x + 63 = 167
4x^2 + 32x - 107 = 0

At this point, use the quadratic formula and x will equal about 2.5.

Answer 2

The answer is 2.5 . Hoped this helped

What are the coordinates of the vertices of a rectangle with an perimeter of 12 units and an area of 5 sq. units.

Answers

Answer: The perimeter of the rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

The area of the rectangle is A = L w, A = 8 x 5 = 40 units to the 2nd power

Step-by-step explanation:

In order to solve this problem you need to find the distances between the vertices. By inspection the points (5,3) and (5,-2) form one the of the rectangle w = √ ( 5-5)2 + ( -2-3)2 = 5

The length can be obtained by finding distance between the points (5,3) and ( -3,3),

L = √(3-3)2+(-3-5)2 = 8

= 26 units

The perimeter of the rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

The rectangle is the quadrilateral with 4 right angles. It could also be defined as, an equiangular quadrilateral, since equiangular means that the all of this angles are = (360°/4 = 90°); and the parallelogram containing a right angle. A rectangle with 4 sides of equal length is a square. The term oblong is occasionally used to refer to a non square rectangle.

The area of rectangle is A = L w, A = 8 x 5 = 40 units to the 2nd power

In order to solve this question you want to find the distances between the vertices. By inspection the points (5,3) and (5,-2) form 1 the of the rectangle w = √ ( 5-5)2 + ( -2-3)2 = 5

The length can be obtained by finding distance between the points (5,3) and ( -3,3),

L = √(3-3)2+(-3-5)2 = 8

The perimeter of rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

Let’s find the slope of this equation

Slope formula:

(y2-y1/x2-x1)

Plug things in

(-3000-0/20-0)

(-3000/20)

Condense the fraction

Slope = -150 or lowering 150 feet per minute.

Let’s get point slope form, add in some points.

Point slope form:

y - y1 = -150(x - x1)

Plug things in

y - (-3000) = -150(x - 20)

y + 3000 = -150x + 3000

Subtract 3009

y = -150x

Plug in -36000 for y

(-36000) = -150x

Divide by -150

x = 240

You are correct, it took 240 minutes.

This is wrong

Next, C

y = x + 470

Let’s try 5
