Suppose a quilt made up of squares has a length-to-width ratio of 5 to 4. The length of the quilt is 5x inches. The quilt can be

made slightly larger by adding a border of 1-inch squares all the way around the perimeter of the quilt. Write a polynomial expression for the area of the larger quilt.

Answer:

20x + 18x + 4

Step-by-step explanation:

The quilt was in a 5:4 ratio, which meant the length was 5x and the width was 4x. The larger quilt added a border of 1-inch squares, which meant that the length & width would increase by 2 inches.

We have the area as (5x + 2)(4x + 2) = 20x + 10x + 8x  + 4

                                                             = 20x + 18x + 4

Solution: 20x + 18x + 4

Infinitely many because if you take the top equation and multiply it by 2 you get the same equation. That means that any number you plug in for x is a solution

snow_tiger [21]

Answer:

c) none of the above

Step-by-step explanation:

this is because we should put the equation like:

1/3 - (-4/3) because the distance is 5 units and

1/3 + 4/3 = 5/3

this is because (-) × (-) = (+)

Find the perimeter of the given triangle
trasher [3.6K]

Here it is given that the triangles ABP and DCR are similars, therefore we use the ratio rule which states that

corresponding sides of similar triangles are in same proprtion .

\frac{AB}{DC} = \frac{BP}{CR}

that gives

7/10 = BP/11

7*11=10BP

BP=7.7

Again using the ratio rule

\frac{AB}{DC} = \frac{AP}{DR}

7/10 = AP/6

42 = 10AP

AP = 4.2

Perimeter= AB+BP+AP = 7+7.7+4.2 = 18.9

Correct option is A.

Divide 100 in a ratio of 5:3
bixtya [17]

Answer:

 62.5 : 37.5

Step-by-step explanation:

When we divide 100 into 5:3 ratio the parts we make need to add up to 100

5parts +3 parts = 8 parts

100/8 parts = 12.5 are in each part

12.5*5 : 12.5*3

 62.5 : 37.5

check our answer 62.5+37.5 = 100 ✅
