Since, a rectangle with a diagonal of length x is twice as long as it is wide, the area of the rectangle is (B) 2x²/5

Given that we have a rectangle with a diagonal of length x is twice as long as it is wide.

Let

Given that the length of diagonal, x is twice as long as it is wide, we have that

L = 2W

Also, since it is rectangle, we have that

D² = L² + W²

D² = (2W)² + W²

D² = 4W² + W²

x² = 5W²

W² = x²/5

W = x/√5

W = x√5/5

Since the length of the rectangle, L = 2W, we have that

L = 2W

= 2x√5/5

The area of the rectangle is given by A = LW where

So, A = LW

= 2x√5/5 × x√5/5

= 2x² × 5/25

= 2x²/5

So, the area of the rectangle is (B) 2x²/5

Answer:

It is D

Step-by-step explanation:

Since there is two x's on 3 they put three twice to match it

The value of the length of the newspaper is 21.52 inches and the width is 22.74 inches.

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Lets say,

Length of newspaper = l

Width of newspaper = w

Area of newspaper ( rectangle ) = l × w

Now,

Length is about 1.22 times its width.

So,

l = 1.22w

By substituting

1.22w × w = 630.92

1.22w² = 630.92

w² = 517.147

w = 22.74 inches

So,

l = 1.22 × 22.74

l = 21.52 inches

Hence "The value of the length of the newspaper is 21.52 inches and the width is 22.74 inches".

Step-by-step explanation:

Here, we want to calculate the number of ways in which the selection can be made

We have this as follows;

Since we have style starting line up already, it means a choice of 5 has been made from the 13 already. What is left is to make a selection of 3 from 5

To do this, we simply apply the combination formula

that would be;

5 C 3 = 10 ways

Answer:

0 (undefined)

Step-by-step explanation:

distribute on the left side first:

-4(3k-6)-4k

so -12k+24-4k

combine like terms

-16k+24

now the right side

-8k+24-4k

combine like terms

-12k+24

so it'll look like this

-16k+24=-12k+24

add -12k to the left

-4k+24=24

so then subtract 24

that'll leave you with 0
