A(n) __________ is two expressions separated by an equal sign.
equation |
|
formula |
|
problem |
|
expression |
An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
The dimensions of this trapezoid are a = 4, b = 6, c = 7, d = 6, and h = 3. What is the area?
| 18 | |
| 22 | |
| 10 | |
| 26 |
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(6 + 6)(3)
a = ½(12)(3)
a = ½(36) = \( \frac{36}{2} \)
a = 18
If a = c = 8, b = d = 6, and the blue angle = 58°, what is the area of this parallelogram?
| 48 | |
| 81 | |
| 54 | |
| 12 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 8 x 6
a = 48
If BD = 23 and AD = 26, AB = ?
| 14 | |
| 3 | |
| 12 | |
| 17 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDWhich of the following expressions contains exactly two terms?
polynomial |
|
quadratic |
|
monomial |
|
binomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
