The complete question is:
Henry knows that the circumference of a circle is 18π inches. What is the area of the circle?
Solution:
Circumference (C) of the circle can be written as:
Using this value of radius, we can find the Area(A) of the circle.
Therefore, area of the circle having a circumference of 18π inches will be 81π inches²

Answer:
Given the equation: 9(x+1) = 25+x
Distributive property of multiplication over addition states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately i,e,
Then, by using distributive property on LHS in the given equation we have;
9x+9 =25 +x
Subtract 9 from both the sides;
9x+9-9=25+x-9
Simplify:
9x = 16+x
Subtract x from both the sides we get;
9x-x=16+x-x
Simplify:
8x=16
Divide both sides by 8 we have;
On Simplify:
x =2
Therefore, the value of x for the equation 9(x+1) = 25+x is, 2
