Answer:

  260 square feet

Step-by-step explanation:

The area of a rectangle is given by the formula ...

  A = LW

The area of two same-size rectangular rooms will be double the area of one of them.

__

<h3>room area</h3>

Each room has an area of ...

  A = LW = (13 ft)(10 ft) = 130 ft²

<h3>carpet order</h3>

The order for carpet must be for 2 times the area of one room:

  carpet order = 2 × 130 ft² = 260 ft²

Jerry should order 260 square feet of carpet.

Find the dimensions of the rectangle with area 289 square inches that has minimum perimeter, and then find the minimum perimeter
nalin [4]
 <span>To minimize the perimeter you should always have a square. 
sqrt(289) = 17 
The dimensions should be 17 X 17 

To see , try starting at length 1, and gradually increase the length. 
The height decreases at a faster rate than the length increases, up until you reach a square. 

Or if you want to use algebra, Say the width is 17-x 
Then the length is 289/(17-x) 

Now, this is bigger than 17+x, as shown here: 
289/(17-x) > 17+x 
289 > 289 - x^2 
which is true. 
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17 

Again, the dimensions should be a square. 17 X 17.</span>

Solve this equation. -4(p+2)+8=2(p-1)-7p+15
ratelena [41]
Hey there! 

First we have to distribute! 

-4 (p +2) = +8 = 2(p - 1) -7p + 15 \\  -4(p) + -4(2) + 8 = 2(p) +-2 + -7p + 15

Now, we have to combine our like terms 

-4p + (-8 + 8) = 2p + (-7p) + (-2) + 15 &#10;

Once we solve all the like-terms we get 

-4p = 5p +13

Now, we have to add 5p to each of your sides 

-4p + 5p \\ = -5p + 13 + 5p

Solve that part of the equation 

p= 13

Good luck on your assignment and enjoy your assignment
