Answer:

D

Step-by-step explanation:

The equation to determine the length and width of the rug is 21 = w² + 4w.

A rectangle is a four sided figure with opposite sides are equal .

Area of a rectangle = Length x width

Given that A rectangular rug with an area of 21 square feet.

The rug is 4 feet longer than it is wide.

Let 'l " be the length of the rug and 'w' be the width of the rug

Length is 4 feet longer than its width

l = w + 4

Area is 21 square feet.

Area = l x w

21 = (w + 4)w

21 = w² + 4w

The equation to determine the length and width of the rug is 21 = w² + 4w.

So width is 3 ft

Length = w +4

length = 3+4= 7 feet

Thus Length of the rug is 7 feet

Length of rug = 7 feet

width of the rug = 4 feet

Step-by-step explanation:

Answer:

so angle a is 60 and angle c is 80. you add those together to get 140. you then subtract 140 from 180 and you get 40. lastly you divide 40 by 2 and you get 20 for x.

Answer:

Wrong dude.

Step-by-step explanation:

1/4 + 50 = 50.25

(Is this a satire question)?

Step-by-step explanation:

9x = 360 (circle angle = 60°)

x = 40

2y + 40 = 180 (sum of interior angles of a triangle)

2y = 180 - 40

2y = 140

y = 70

Answer:

A. 5/9

explanation:

The answer is A.

Multiply the fractions.

You can use a calculator online for that. I did and it said 5/9.

When multiplied you get 10/18 and then simplify its 5/9

None of these are right

y=$350 because that is her total.

m=$25 because each game cost that.

B=$200 because that's how much the console cost.

$350=$25x+$200

Answer:

1,872

Step-by-step explanation:

First you have to multiply 156 x 12 and when you get the answer the answer will be 1,872. Hopefully this helps you. :)

Answer:

im not sure if it makes any sense but 156 divided by 12 = 13

Answer:

The card with the highest interest rate is usually the one that will cause you the most financial pain. The national average interest rate on a credit card is 15.2 percent, so if you bought a $1,000 …

Answer:

Paying off the highest interest rate credit card first makes the most mathematical sense because it will save you more money and allow you to redirect funds to other financial goals faster. Paying off the highest interest rate first is better because this way you get to avoid financial problems and avoid having to pay too much money of interest since the card with the highest interest rate is usually the one that will cause you the most financial pain.

Answer:

[tex]3 \sqrt{11} [/tex]

Step-by-step explanation:

Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

[tex] {a}^{2} + {b}^{2} = c {}^{2} [/tex]

where a and b are the legs and c is the hypotenuse l.

Let plug it in

[tex] {a}^{2} + 15 {}^{2} = {18}^{2} [/tex]

[tex] {a }^{2} + 225 = 324[/tex]

[tex] {a}^{2} = 99[/tex]

[tex]a = \sqrt{99} [/tex]

[tex]a = \sqrt{9 \times 11} [/tex]

[tex]a = 3 \sqrt{11} [/tex]

Answer:monthly rent of a 1-bedroom apartment= $280

Step-by-step explanation:

Let the  cost of 1 bed room apartment = x

And the cost of two bedroom apartment= 2x-40

Since the cost of of two bedroom apartment = $520  

Then the cost of one bed room part will be expressed as

520= 2x- 40

520+40 = 2x

560= 2x

x= 560/ 2

x= 280

Therefore the  cost of 1 bed room apartment = x= $280

Answer:

i believe the answer is 46. good luck!

Answer:

x = -6

Step-by-step explanation:

A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.

Actually Welcome to the Concept of the areas.

Since we know that, radius = diameter /2

here, => d = 2r ,

hence we use the formula as,
