If side x = 10cm, side y = 12cm, and side z = 15cm what is the perimeter of this triangle?
| 29cm | |
| 35cm | |
| 28cm | |
| 37cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 10cm + 12cm + 15cm = 37cm
The dimensions of this trapezoid are a = 6, b = 8, c = 9, d = 2, and h = 5. What is the area?
| 26 | |
| 20 | |
| 10\(\frac{1}{2}\) | |
| 25 |
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(8 + 2)(5)
a = ½(10)(5)
a = ½(50) = \( \frac{50}{2} \)
a = 25
Breaking apart a quadratic expression into a pair of binomials is called:
deconstructing |
|
squaring |
|
normalizing |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
A trapezoid is a quadrilateral with one set of __________ sides.
equal angle |
|
parallel |
|
equal length |
|
right angle |
A trapezoid is a quadrilateral with one set of parallel sides.
The dimensions of this cube are height (h) = 9, length (l) = 5, and width (w) = 7. What is the volume?
| 72 | |
| 315 | |
| 80 | |
| 24 |
The volume of a cube is height x length x width:
v = h x l x w
v = 9 x 5 x 7
v = 315
