To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?

84% Answer Correctly

Odd

First

Last

Inside
Solution

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.

2

If BD = 13 and AD = 22, AB = ?

76% Answer Correctly
19
9
14
8
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 = 22 - 13
AB = 9

3

The endpoints of this line segment are at (-2, -5) and (2, 1). What is the slope of this line?

46% Answer Correctly
-3
1\(\frac{1}{2}\)
2\(\frac{1}{2}\)
-2\(\frac{1}{2}\)
Solution

The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, -5) and (2, 1) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(1.0) - (-5.0)}{(2) - (-2)} \) = \( \frac{6}{4} \)
m = 1\(\frac{1}{2}\)

4

What is 7a - 6a?

80% Answer Correctly
42a2
42a
13a2
1a
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 - 6a = 1a

5

Simplify (3a)(4ab) + (2a2)(5b).

65% Answer Correctly
49a2b
-2a2b
22a2b
22ab2
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)(4ab) + (2a2)(5b)
(3 x 4)(a x a x b) + (2 x 5)(a2 x b)
(12)(a1+1 x b) + (10)(a2b)
12a2b + 10a2b
22a2b
