Answer:
No solutions, 0
Step-by-step explanation:
When you solve a equation and get an answer of n = s (I am just using n and s a placeholders. They that be any number.) where n ≠ s, then there are no solutions to the equation.
In this case, whenever you see a number directly in front of x, multiplying itself by/with x, it's a coefficient.
That applies to the numbers 7, 9, and 2 if I'm reading this correctly. Hope this helps!

The equation to use to find the radius of a circle is 
The equation to use to find the area of a circle is 
First, add 
inches to the diameter of 
inches. You will get 
inches.
Second, you will want to find the radius. Substitute for 
. Solve to get the radius.
The radius is 
inches.
Next, you substitute for 
in the area equation. Solve to get the area.
Answer: (a) 9
<u>Step-by-step explanation:</u>
1st multiple of 3: 1(3x)
2nd multiple of 3: 2(3x)
3rd multiple of 3: 3(3x)
Sum = 4(1st multiple of 3) + 6
1(3x) + 2(3x) + 3(3x) = 4(3x) + 6
3x + 6x + 9x = 12x + 6
18x = 12x + 6
6x = 6
x = 1
Largest (3rd) multiple is: 3(3x)
= 9x
= 9 · 1
= 9
