Answer:

x = -7

Step-by-step explanation:

3(x+7) = -15

First, distributive property. Therefore, you multiply 3 with x and 7

3x + 21 = -15

Then, you need x to be isolated. So you will have to -21 from +21 on both sides of the equation to make it balanced.

3x + 21 = -15

-21 -21 (21 will be canceled from the left side of the equation)

3x = -35

Lastly, you need to divide 3 from both sides of the equation, as 3 is multiplied with x.

3x = -35

3 3 (3 will be canceled from the left side of the equation)

x = -7

Multiply 2nd equation by 3 and add to first
9x-3y=-2
-9x+3y=-9 +
0x+0y=-7

0=-7

The area of the David's pantry = 10 square feet.

The length of the pantry = 5 feet.

<h3>Define the term area of the rectangle?</h3>

The territory inhabited by a rectangle inside its 4 sides or limits is known as its area.
The area of such a rectangle is determined by its sides. Essentially, the formula calculating area is equivalent to the product of the rectangle's length and breadth.

For the given question.

David's kitchen is 60 square feet in size.
The kitchen is six times the size of the living room.

Thus,

Area of kitchen = 6 x area of the pantry

60 = 6 x area of the pantry

area of the pantry = 60 / 6 = 10 square feet.

Area of the pantry = length x breadth

10 = length x 2

length = 10/2 = 5 feet.

Thus, the length of the pantry is found as the 5 feet.

What is the exact area of a circle with a diameter of 20 cm?

Kisachek [45]

Hi there! The answer is 100πcm^2

The radius of a circle can be found by dividing the diameter by 2. In other words : the radius is half of the diameter.
Therefore, the radius of a circle with a diameter of 20 cm is 10 cm.

The exact area of a circle can be found using the following formula:
$a = \pi \times \: {r}^{2} \\ with \\ a = area \\ r = radius$

In order to find our answer, we need to plug in the data from the question.
$a = \pi \: \times {10}^{2} = 100\pi$

Hence, the answer is 100πcm^2.
