What is 2a + 4a?

80% Answer Correctly
6a
-2a2
8a
6
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.

2a + 4a = 6a

2

What is 5a3 + 6a3?

74% Answer Correctly
11
11a6
11a3
30a3
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.

5a3 + 6a3 = 11a3

3

Which of the following statements about a parallelogram is not true?

49% Answer Correctly

the area of a parallelogram is base x height

opposite sides and adjacent angles are equal

the perimeter of a parallelogram is the sum of the lengths of all sides

a parallelogram is a quadrilateral
Solution

A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).

4

If a = c = 1, b = d = 2, and the blue angle = 59°, what is the area of this parallelogram?

65% Answer Correctly
48
1
8
2
Solution

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

a = l x w
a = a x b
a = 1 x 2
a = 2

Simplify (3a)(3ab) - (4a2)(8b).

59% Answer Correctly
41ab2
72a2b
41a2b
-23a2b
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.

(3a)(3ab) - (4a2)(8b)
(3 x 3)(a x a x b) - (4 x 8)(a2 x b)
(9)(a1+1 x b) - (32)(a2b)
9a2b - 32a2b
-23a2b
