What is the circumference of a circle with a diameter of 10?

71% Answer Correctly

	11π
	10π
	8π
	2π

Solution

The formula for circumference is circle diameter x π:

c = πd
c = 10π

A(n) __________ is two expressions separated by an equal sign.

77% Answer Correctly

	formula
	expression
	problem
	equation

Solution

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.

If BD = 26 and AD = 27, AB = ?

76% Answer Correctly

	1
	9
	3
	18

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 27 - 26
AB = 1

What is the area of a circle with a diameter of 8?

70% Answer Correctly

	9π
	25π
	16π
	8π

Solution

The formula for area is πr². Radius is circle \( \frac{diameter}{2} \):

r = \( \frac{d}{2} \)
r = \( \frac{8}{2} \)
r = 4
a = πr²
a = π(4²)
a = 16π

Breaking apart a quadratic expression into a pair of binomials is called:

75% Answer Correctly

	normalizing
	deconstructing
	squaring
	factoring

Solution

To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
