1

If a = c = 8, b = d = 9, and the blue angle = 57°, what is the area of this parallelogram?

65% Answer Correctly
72
36
2
12

Solution

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

a = l x w
a = a x b
a = 8 x 9
a = 72


2

What is 7a - 9a?

79% Answer Correctly
-2a
63a2
16
-2a2

Solution

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

7a - 9a = -2a


3

If AD = 21 and BD = 12, AB = ?

75% Answer Correctly
8
9
18
3

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 = 21 - 12
AB = 9


4

Simplify (7a)(7ab) + (2a2)(5b).

65% Answer Correctly
98ab2
39ab2
-39ab2
59a2b

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.

(7a)(7ab) + (2a2)(5b)
(7 x 7)(a x a x b) + (2 x 5)(a2 x b)
(49)(a1+1 x b) + (10)(a2b)
49a2b + 10a2b
59a2b


5

If a = c = 1, b = d = 4, what is the area of this rectangle?

79% Answer Correctly
32
4
49
36

Solution

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

a = l x w
a = a x b
a = 1 x 4
a = 4
