Create an equation with the indicated number of solutions.

GenaCL600 [577]

An equation that doesn't have a solution would have to end up as something impossible when you solve it all out, like
5=3.

When you simplify your equation out, you get

3x-4=3x+?

Subtract 3x from both sides.

-4=?

From this, you can tell that you need to out something in the ? that will make the equation false, or something that doesn't equal -4.

You could put anything in the ? as long as it is not -4.

Hope this helps!

What is the value of x in the triangle below? Round your answer to the nearest tenth if necessary. Please show your work! tyy

Tanzania [10]

Answer:

x = 14.3

Step-by-step explanation:

To find one of the sides, we can use the pythagorean theorem:

a² + b² = c²

a² = c² - b²

a = √c² -b²

a = √(20)² -( 14)²

a = 14.3

Luda [366]

Answer:

The width of the door is 4 feet.

Step-by-step explanation:

Given,

For house,

Length = 10 ft

Width = 12 ft

Length of door = 8 ft

Quantity of wood used to cover the front of house = 88 sq. ft

we have to find the width of the door.

Solution,

Since the front of the house is in rectangular shape.

So we use the formula of area of rectangle, i.e. length times width.

Area of the front of the house = $10\times12=120\ ft^2$

Let the width of the door be 'w'.

So, area = $8\times w=8w$

Now according to question,

Ashley does not want to cover her 8 foot tall front door.

So we can say that;

The quantity of wood used to cover the front of the house is equal to area of the front of the house minus area of the door.

Now we substitute the given values;

$88=120-8w$

combining the like terms, we get;

$8w=120-88\\\\8w=32$

Now dividing both side by '8' using division property, we get;

$\frac{8w}{8}=\frac{32}{8}\\\\w=4\ ft$

Hence The width of the door is 4 feet.
