Which of the following statements about math operations is incorrect?

70% Answer Correctly

	all of these statements are correct
	you can multiply monomials that have different variables and different exponents
	you can subtract monomials that have the same variable and the same exponent
	you can add monomials that have the same variable and the same exponent

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.

If BD = 3 and AD = 13, AB = ?

75% Answer Correctly

	9
	7
	10
	4

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 = 13 - 3
AB = 10

Which of the following expressions contains exactly two terms?

82% Answer Correctly

	polynomial
	monomial
	quadratic
	binomial

Solution

A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.

Which of the following is not a part of PEMDAS, the acronym for math order of operations?

88% Answer Correctly

	exponents
	division
	pairs
	addition

Solution

When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)

The dimensions of this cylinder are height (h) = 2 and radius (r) = 1. What is the surface area?

48% Answer Correctly

	324π
	156π
	240π
	6π

Solution

The surface area of a cylinder is 2πr² + 2πrh:

sa = 2πr² + 2πrh
sa = 2π(1²) + 2π(1 x 2)
sa = 2π(1) + 2π(2)
sa = (2 x 1)π + (2 x 2)π
sa = 2π + 4π
sa = 6π
