Answer:

-6x^2 +5xy - 6x

Step-by-step explanation:

Remember PEMDAS.

First distribute -5x into (x-y+1), as well as x into (x+1)

distributing first part: -5x^2 + 5xy - 5x ( remember, subtracting a negative is like adding.)

distributing second part: -x^2 - x (These are both negative due to the - in front of the X in the original problem.).

Then just simplify it by adding <em>like terms</em> (terms with the same variables and powers.). -5x^2 + 5xy - 5x - x^2 - x

-6x^2 +5xy - 6x

Answer: -6x^2 +5xy - 6x

Answer: Cylinder 1 - 25.1327412283 cubic cm
Cylinder 2 - 100.5309469149 cubic cm
Cylinder 3 - 226.1946710585 cubic cm

For each of the cylinders, we will need to use the same formula, h(pi(r squared)).

Cylinder 1 - 8(pi(1 squared)). 1 squared = 1. pi × 1 = 3.1415926536. 3.1415926536 × 8 = 25.1327412283 cubic cm.

Cylinder 2 - 8(pi(2 squared)). 2 squared = 4. 4 × pi = 12.5663706144. 12.5663706144 × 8 = 100.5309469149 cubic cm.

Cylinder 3 - 8(pi(3 squared)). 3 squared = 9. 9 × pi = 28.2743338823. 28.2743338823 × 8 = 226.1946710585 cubic cm.

- Hope it helps!
