1

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

54% Answer Correctly

equilateral and right

isosceles and right

equilateral, 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.

2

Which of the following statements about math operations is incorrect?

71% Answer Correctly

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

all of these statements are correct

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

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.

3

If a = 1, b = 6, c = 6, and d = 2, what is the perimeter of this quadrilateral?

88% Answer Correctly
25
15
20
16
Solution

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 1 + 6 + 6 + 2
p = 15

4

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

91% Answer Correctly

division

exponents

addition

pairs
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.)

5

Simplify (4a)(5ab) - (8a2)(4b).

62% Answer Correctly
108ab2
12ab2
52ab2
-12a2b
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)(5ab) - (8a2)(4b)
(4 x 5)(a x a x b) - (8 x 4)(a2 x b)
(20)(a1+1 x b) - (32)(a2b)
20a2b - 32a2b
-12a2b
