Simplify (5a)(5ab) + (3a2)(8b).
| ab2 | |
| 110a2b | |
| -a2b | |
| 49a2b |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
(5a)(5ab) + (3a2)(8b)
(5 x 5)(a x a x b) + (3 x 8)(a2 x b)
(25)(a1+1 x b) + (24)(a2b)
25a2b + 24a2b
49a2b

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
2lw x 2wh + 2lh |
|
h2 x l2 x w2 |
|
lw x wh + lh |
|
h x l x w |
A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.
The dimensions of this cylinder are height (h) = 8 and radius (r) = 6. What is the volume?
| 288π | |
| 112π | |
| 28π | |
| 243π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(62 x 8)
v = 288π
