Answer:

2624

Step-by-step explanation:

Let the second digit be X. Therefore the first digit would be (1/3)X. The third digit would be 8-X and the fourth digit would be 8-X+2 or 10-X.

The last hint is that all the digits add up to 14, so

(1/3)X + X + (8-X) + (10-X) = 14

Solving for X gets you X = 6. If you plug the X value back in to satisfy the conditions, you get 2624.

A rectangle has an area of 36 inches squared. Write an equation to show how the length (l) varies inversely the width (w).
Anastaziya [24]
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36

Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.

Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x

A rectangle has an area of 20 cm^2. What will the area be if the rectangle tripled in size?
antoniya [11.8K]

Answer:

  180 cm^2

Step-by-step explanation:

For similar figures the ratio of areas is the square of the ratio of linear dimensions.

We take "tripled in size" to mean that the linear dimensions of the larger rectangle are 3 times those of the smaller rectangle. That means the area of the larger rectangle will be 3² = 9 times the area of the smaller one.

  Area = (3²)(20 cm²) = 180 cm² . . . . area after tripled in size
