Answer:
The number is 10
Step-by-step explanation:
Let x be the number
product is multiply
12 + (2x) = 4x -8
Subtract 2x from each side
12+2x-2x = 4x-2x-8
12 = 2x-8
Add 8 to each side
12+8 = 2x-8+8
20 = 2x
Divide by 2
20/2 = 2x/2
10 =x
Answer:
C
Step-by-step explanation:
Since the 7 swim teachers had about the same amount of students, you can divide 137 by 7, which comes out to about 20.
Answer:
10x + 9
Step-by-step explanation:
3(2x + 2) +4x + 3
=> 6x + 6 + 4x + 3
=> 10x + 9
Therefore, 10x + 9 is the solved equation.
Hoped this helped.

Hello!</h2>
The answer is:
The fourth graph.
<h2>
Why?</h2>
We are given the following equation:

Then, we need to find the graph of f(x+2) that will be equal to:


Now, finding the x-axis interception, making "y" equal to 0, we have:


Therefore, the x-axis interception point is located at (-2,0), it matches with the fourth graph.
Now, finding the y-axis interception, making "x" equal to 0, we have:


Therefore, the y-axis interception point is located at (0,2), it matches with the fourth graph.
Hence, we have that the graph of f(x+2) is the fourth graph since the second graph function cuts the x-axis at -2 and the y-axis at 2.
Have a nice day!
Answer:
40π in^2
Step-by-step explanation:
360°/72°=5
so, each of the two shaded regions are 1/5 of the circle.
the formula for finding the area of a circle is πr^2, so:
area for one of the shaded regions:
1/5πr^2
1/5π(10)^2
1/5π100
20π in^2
this means that the area for one of the shaded regions is 20π. however, since there are two of them:
2(20π)=40π
so, the area of the shaded regions is 40πin^2
