If a = 5, b = 5, c = 6, and d = 9, what is the perimeter of this quadrilateral?
| 14 | |
| 24 | |
| 25 | |
| 21 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 5 + 5 + 6 + 9
p = 25
Which of the following expressions contains exactly two terms?
binomial |
|
monomial |
|
polynomial |
|
quadratic |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
What is the circumference of a circle with a diameter of 6?
| 18π | |
| 28π | |
| 7π | |
| 6π |
The formula for circumference is circle diameter x π:
c = πd
c = 6π
If the base of this triangle is 2 and the height is 5, what is the area?
| 5 | |
| 84\(\frac{1}{2}\) | |
| 24 | |
| 49\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 2 x 5 = \( \frac{10}{2} \) = 5
What is 4a - 9a?
| -5a2 | |
| 13a2 | |
| 36a2 | |
| -5a |
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.
4a - 9a = -5a
