well, replace all x with the number 12

-4(12-3)+5(12) = 24

-4(9) +60 = 24

-36+60 = 24

24 = 24

<em>Hope this helps!</em>

A triangle is placed in a semicircle with a radius of 9ft, as shown below. Find the area of the shaded region.
Arturiano [62]

The height is given as 9 ft. this is also the radius of the circle.

The base of the triangle would be 2 times the radius = 18 feet.

The area of the triangle is 1/2 x 9 x 18 = 81 square feet.

The area of the semi circle is : 1/2 x PI x r^2 = 1/2 x 3.14 x 9^2 = 127.17

The area of the shaded region is the area of the triangle minus the area of the semi circle:

127.17 - 81 = 46.17 square feet.

2x+3x-x+10x+14=-42 <br><br>3 step equation
vodka [1.7K]
1. We want to add all alike terms and follow GEMDAS as well. Addition first 2x+3x=5x ,then -x(which is equal to -1x) + 10x = 9x. Now we add 5x + 9x = 14x.
Right now the equation looks like:
14x + 14 = -42

2. Now we process the equation,
Subtract 14 from the left side, but what u do to one side u do to the other so now the equation looks like:
14x = -56

3. Now we are almost finished last step.
14x changes to x and we divide -56 by 14 which equals -4. The answer is
X = -4
