Answer:
(6-√21, 6+√21)
Step-by-step explanation:
x^2 - 12x = -15
(x - 6)^2 - 36 = -15
(x - 6)^2 = 21
x - 6 = ± √21
x = 6 ± √21
Hello from MrBillDoesMath!
Answer:

Discussion:
2 tens = 2 * 10 = 20
13 ones = 13 * 1 13
=> 2 tens + 13 ones = 20 + 13 = 33
Thank you,

➷ As there would be 2 circles, you'd need to find the area of a circle and then multiply it by 2
To start with, we can use this:
2 (
r^2)
^^ This represents the surface area of the two circles
A cylinder also has a rectangle which is rolled to form the shape
As we know, the formula of a rectangles area is length x width
The width of the rectangle would be equal to the circumference of a circle
circumference of circle = 
The length of the rectangle would be the height of the cylinder
We can use this:

This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.
