Odd |
|
First |
|

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 dimensions of this cylinder are height (h) = 6 and radius (r) = 4. What is the surface area?
| 120π | |
| 96π | |
| 80π | |
| 216π |
The surface area of a cylinder is 2πr2 + 2πrh:
sa = 2πr2 + 2πrh
sa = 2π(42) + 2π(4 x 6)
sa = 2π(16) + 2π(24)
sa = (2 x 16)π + (2 x 24)π
sa = 32π + 48π
sa = 80π
What is 7a - 5a?
| 2a | |
| 35a | |
| 12 | |
| 2a2 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
7a - 5a = 2a
The dimensions of this cube are height (h) = 4, length (l) = 7, and width (w) = 4. What is the volume?
| 112 | |
| 42 | |
| 80 | |
| 120 |
The volume of a cube is height x length x width:
v = h x l x w
v = 4 x 7 x 4
v = 112
If a = c = 8, b = d = 9, and the blue angle = 71°, what is the area of this parallelogram?
| 8 | |
| 24 | |
| 72 | |
| 56 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 8 x 9
a = 72
