1

What is the area of a circle with a radius of 5?

70% Answer Correctly
36π
3π
25π
2π
Solution

The formula for area is πr2:

a = πr2
a = π(52)
a = 25π

2

Which of the following statements about math operations is incorrect?

71% Answer Correctly

you can subtract monomials that have the same variable and the same exponent

you can multiply monomials that have different variables and different exponents

you can add monomials that have the same variable and the same exponent

all of these statements are correct
Solution

You can only add or subtract monomials that have the same variable and the same exponent. For example, 2a + 4a = 6a and 4a2 - a2 = 3a2 but 2a + 4b and 7a - 3b cannot be combined. However, you can multiply and divide monomials with unlike terms. For example, 2a x 6b = 12ab.

3

If the base of this triangle is 2 and the height is 3, what is the area?

59% Answer Correctly
24
3
32
42
Solution

The area of a triangle is equal to ½ base x height:

a = ½bh
a = ½ x 2 x 3 = \( \frac{6}{2} \) = 3

4

Solve for z:
z2 + z - 12 = 0

58% Answer Correctly
2 or -1
3 or -4
9 or 2
8 or 2
Solution

The first step to solve a quadratic equation that's set to zero is to factor the quadratic equation:

z2 + z - 12 = 0
(z - 3)(z + 4) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, either (z - 3) or (z + 4) must equal zero:

If (z - 3) = 0, z must equal 3
If (z + 4) = 0, z must equal -4

So the solution is that z = 3 or -4

5

A(n) __________ is to a parallelogram as a square is to a rectangle.

52% Answer Correctly

quadrilateral

rhombus

trapezoid

triangle
Solution

A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
