Answer:
The first one, you cannot factor because the two values do not share any common factors. Hence, the answer would just be:
a. 51x-25
The other one, we can factorise to:
b. 3x(4-x)
Step-by-step explanation:
For the second option:
Common factor between 12x and 3x^2 is 3x.
Take this out to the front, we are left with:
3x(4-x)

Answer:
2770.9 in³
Step-by-step explanation:
A cylinder has a base radius of 7in and a height of 18in. What is its volume in cubic inch to the nearest tenths place?
The formula for the volume of a cylinder is given as:
πr²h
r = radius = 7 in
h = height = 18 in
Hence:
Volume of the cylinder = π × 7² × 18
= 2770.88472 in³
Approximately to the nearest tenth = 2770.9 in³
1/12th of 60 is 5 (5 x 12 = 60)
