Which of the following expressions contains exactly two terms?
monomial |
|
quadratic |
|
polynomial |
|
binomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If a = 7, b = 3, c = 2, and d = 5, what is the perimeter of this quadrilateral?
| 24 | |
| 17 | |
| 14 | |
| 16 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 7 + 3 + 2 + 5
p = 17
If a = c = 8, b = d = 1, and the blue angle = 65°, what is the area of this parallelogram?
| 4 | |
| 9 | |
| 28 | |
| 8 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 8 x 1
a = 8
If side x = 12cm, side y = 8cm, and side z = 8cm what is the perimeter of this triangle?
| 29cm | |
| 28cm | |
| 35cm | |
| 43cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 12cm + 8cm + 8cm = 28cm
A cylinder with a radius (r) and a height (h) has a surface area of:
4π r2 |
|
2(π r2) + 2π rh |
|
π r2h2 |
|
π r2h |
A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.
