Step-by-step explanation:
Simplifying
1.5x + -2.5x = 3
Combine like terms: 1.5x + -2.5x = -1x
-1x = 3
Solving
-1x = 3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-1'.
x = -3
Simplifying
x = -3
Answer:
A = 81π cm²
Step-by-step explanation:
The formula for area of a circle is A = πr², where r is the radius. The radius is half the diameter, so our radius for this problem is
18/2 = 9. So the area is..
A = π(9²) = π(81)
A = 81π cm²
