Odd |
|
Last |

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.
On this circle, a line segment connecting point A to point D is called:
chord |
|
radius |
|
diameter |
|
circumference |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).

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.
(2a)(5ab) + (2a2)(8b)
(2 x 5)(a x a x b) + (2 x 8)(a2 x b)
(10)(a1+1 x b) + (16)(a2b)
10a2b + 16a2b
26a2b
The dimensions of this cylinder are height (h) = 1 and radius (r) = 9. What is the surface area?
| 132π | |
| 180π | |
| 90π | |
| 96π |
The surface area of a cylinder is 2πr2 + 2πrh:
sa = 2πr2 + 2πrh
sa = 2π(92) + 2π(9 x 1)
sa = 2π(81) + 2π(9)
sa = (2 x 81)π + (2 x 9)π
sa = 162π + 18π
sa = 180π
If a = c = 4, b = d = 1, and the blue angle = 57°, what is the area of this parallelogram?

The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 4 x 1
a = 4
