If a = 6, b = 6, c = 4, and d = 2, what is the perimeter of this quadrilateral?
| 18 | |
| 17 | |
| 24 | |
| 14 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 6 + 6 + 4 + 2
p = 18
Which of the following expressions contains exactly two terms?
quadratic |
|
binomial |
|
polynomial |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
Which of the following statements about a parallelogram is not true?
opposite sides and adjacent angles are equal |
|
a parallelogram is a quadrilateral |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
|
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).
Solve for x:
-7x - 5 < -8 + 9x
| x < \(\frac{1}{6}\) | |
| x < 8 | |
| x < \(\frac{3}{16}\) | |
| x < \(\frac{1}{2}\) |
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.
-7x - 5 < -8 + 9x
-7x < -8 + 9x + 5
-7x - 9x < -8 + 5
-16x < -3
x < \( \frac{-3}{-16} \)
x < \(\frac{3}{16}\)
The dimensions of this cube are height (h) = 5, length (l) = 5, and width (w) = 8. What is the surface area?
| 210 | |
| 102 | |
| 176 | |
| 110 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 5 x 8) + (2 x 8 x 5) + (2 x 5 x 5)
sa = (80) + (80) + (50)
sa = 210
