To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Inside |
|
Odd |
|
First |
|
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.
The formula for the area of a circle is which of the following?
a = π d |
|
a = π r2 |
|
a = π r |
|
a = π d2 |
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
Simplify (y + 9)(y + 3)
| y2 + 6y - 27 | |
| y2 + 12y + 27 | |
| y2 - 12y + 27 | |
| y2 - 6y - 27 |
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:
(y + 9)(y + 3)
(y x y) + (y x 3) + (9 x y) + (9 x 3)
y2 + 3y + 9y + 27
y2 + 12y + 27
The dimensions of this trapezoid are a = 6, b = 9, c = 9, d = 6, and h = 4. What is the area?
| 19\(\frac{1}{2}\) | |
| 34 | |
| 12\(\frac{1}{2}\) | |
| 30 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(9 + 6)(4)
a = ½(15)(4)
a = ½(60) = \( \frac{60}{2} \)
a = 30
On this circle, a line segment connecting point A to point D is called:
radius |
|
chord |
|
circumference |
|
diameter |
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).
