Which of the following statements about math operations is incorrect?

70% Answer Correctly

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

all of these statements are correct

you can multiply monomials that have different variables and different exponents
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.

2

Which of the following expressions contains exactly two terms?

82% Answer Correctly

binomial

monomial

quadratic

polynomial
Solution

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

3

A coordinate grid is composed of which of the following?

88% Answer Correctly

all of these

y-axis

origin

x-axis
Solution

The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.

4

Simplify 4a x 4b.

86% Answer Correctly
16\( \frac{b}{a} \)
16a2b2
16ab
8ab
Solution

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

4a x 4b = (4 x 4) (a x b) = 16ab

5

Which types of triangles will always have at least two sides of equal length?

54% Answer Correctly

equilateral and right

equilateral, isosceles and right

isosceles and right

equilateral and isosceles
Solution

An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
