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.
If side a = 1, side b = 4, what is the length of the hypotenuse of this right triangle?
| 5 | |
| \( \sqrt{20} \) | |
| \( \sqrt{17} \) | |
| \( \sqrt{8} \) |
According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:
c2 = a2 + b2
c2 = 12 + 42
c2 = 1 + 16
c2 = 17
c = \( \sqrt{17} \)
What is the circumference of a circle with a diameter of 11?
| 16π | |
| 20π | |
| 11π | |
| 4π |
The formula for circumference is circle diameter x π:
c = πd
c = 11π
What is 3a3 - 2a3?
| 5a6 | |
| 6a3 | |
| 1a3 | |
| a36 |
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.
3a3 - 2a3 = 1a3
If a = 9, b = 9, c = 4, and d = 4, what is the perimeter of this quadrilateral?
| 24 | |
| 22 | |
| 26 | |
| 27 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 9 + 9 + 4 + 4
p = 26
