The sides of the frame are (12+2x) and (6+2x).
Its area A is 112.

Therefore by equating:
(12+2x)*(6+2x)=112
you can get the answer for x. You will obtain a quadratic equation you have to solve.

Answer:

Step-by-step explanation:

In mathematics, the discount is a type of reduction in the cost price of a product.

Use the diagram below to solve for x and y.

Mrac [35]

Answer:

Option A. x=30,y=42

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles ABC and ZYX have three congruent interior angles

therefore

Triangles are similar

step 1

Find the value of x

$\frac{ZY}{AB}=\frac{ZX}{AC}$

substitute the values

$\frac{20}{x}=\frac{12}{18}$

$x=20*18/12=30\ units$

step 2

Find the value of y

$\frac{ZY}{AB}=\frac{XY}{CB}$

substitute the values

$\frac{20}{30}=\frac{28}{y}$

$y=30*28/20=42\ units$

Mr.hong is a rare coin collector he recently bought a coin valued $5400 it has been determined that the coin will increase in va

marta [7]

Answer:$7,200

Quantities that changed in the problem are

1. The value of the coin

2. The time it took to appreciate to that value

Step-by-step explanation:

Current value = $5,400

Increase in value (monthly) = $30

In 5 years time, the value would increase by

(12*5) * $30 = $1800

Value in five years = current value + increase in value

Value in five years = $5400 + $1800

Value in five years = $7,200

A taxi service charges a flat fee of $1.25 and $0.75 per mile. If Henri has $14.00, which of the following shows the number of m

AlexFokin [52]

Answer: 17 miles

Step-by-step explanation:

The total cost of the taxi service is the flat free and the total amount that is based on the distance. Let x be this distance. The equation that would best represent the situation is,

1.25 + 0.75x = 14

Solving for x gives the answer of 17. Thus, Henri can afford to travel 17 mile
