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

91% Answer Correctly

pairs

division

exponents

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.)

2

If a = c = 9, b = d = 4, and the blue angle = 71°, what is the area of this parallelogram?

66% Answer Correctly
24
9
32
36
Solution

The area of a parallelogram is equal to its length x width:

a = l x w
a = a x b
a = 9 x 4
a = 36

3

If b = -3 and x = -8, what is the value of 6b(b - x)?

69% Answer Correctly
-576
-90
150
441
Solution

To solve this equation, 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.)

6b(b - x)
6(-3)(-3 + 8)
6(-3)(5)
(-18)(5)
-90

4

If a = 3, b = 9, c = 5, and d = 9, what is the perimeter of this quadrilateral?

88% Answer Correctly
19
21
10
26
Solution

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 3 + 9 + 5 + 9
p = 26

5

The dimensions of this cube are height (h) = 9, length (l) = 4, and width (w) = 1. What is the surface area?

51% Answer Correctly
22
382
152
98
Solution

The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):

sa = 2lw + 2wh + 2lh
sa = (2 x 4 x 1) + (2 x 1 x 9) + (2 x 4 x 9)
sa = (8) + (18) + (72)
sa = 98
