To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Inside |
|
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.
Which of the following statements about a parallelogram is not true?
a parallelogram is a quadrilateral |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
opposite sides and adjacent angles are equal |
|
the area of a parallelogram is base x height |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
What is 6a8 + 6a8?
| 0 | |
| a816 | |
| 12a8 | |
| 36a8 |
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.
6a8 + 6a8 = 12a8
Solve for b:
2b + 3 < 1 + 5b
| b < 4 | |
| b < -4 | |
| b < 1\(\frac{1}{2}\) | |
| b < \(\frac{2}{3}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.
2b + 3 < 1 + 5b
2b < 1 + 5b - 3
2b - 5b < 1 - 3
-3b < -2
b < \( \frac{-2}{-3} \)
b < \(\frac{2}{3}\)
Which of the following statements about a triangle is not true?
sum of interior angles = 180° |
|
exterior angle = sum of two adjacent interior angles |
|
area = ½bh |
|
perimeter = sum of side lengths |
A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.
