2x + a = b Subtract a from both sides
2x = b - a Divide both sides by 2
x =

Step-by-step explanation:
10x+9=4x-9
10x-4x+9=4x-4x-9
6x+9=-9
6x-9+9=-9-9
6x=-18
x=-3
Answer:
96π yd² ≈ 301.6 yd²
Step-by-step explanation:
The total surface area of a cylinder, including flat circular top and bottom and curved lateral surface, is given by the formula ...
S = 2πr² + 2πrh . . . . . where r is the radius and h is the height
For a radius of 3 yards and a height of 13 yards, the area is ...
S = 2π(3 yd)² + 2π(3 yd)(13 yd)
S = 18π yd² + 78π yd²
S = 96π yd² ≈ 301.6 yd²
The total surface area is about 301.6 square yards.
