Simplify 5a x 7b.
| 35ab | |
| 35\( \frac{a}{b} \) | |
| 35\( \frac{b}{a} \) | |
| 12ab |
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.
5a x 7b = (5 x 7) (a x b) = 35ab
Solve for c:
6c - 4 = \( \frac{c}{6} \)
| -2\(\frac{2}{11}\) | |
| -\(\frac{36}{55}\) | |
| 1\(\frac{8}{19}\) | |
| \(\frac{24}{35}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
6c - 4 = \( \frac{c}{6} \)
6 x (6c - 4) = c
(6 x 6c) + (6 x -4) = c
36c - 24 = c
36c - 24 - c = 0
36c - c = 24
35c = 24
c = \( \frac{24}{35} \)
c = \(\frac{24}{35}\)
If a = c = 5, b = d = 1, and the blue angle = 57°, what is the area of this parallelogram?

| 5 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 5 x 1
a = 5
If a = c = 8, b = d = 7, what is the area of this rectangle?
| 16 | |
| 36 | |
| 12 | |
| 56 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 8 x 7
a = 56
If the length of AB equals the length of BD, point B __________ this line segment.
