A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
triangle |

A(n) __________ is two expressions separated by an equal sign.
formula |
|
equation |
|
problem |
|
expression |
An equation is two expressions separated by an equal sign. The key to solving equations is to 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.
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Last |
|
Odd |
|
First |
|

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.
Solve for z:
9z + 9 = \( \frac{z}{3} \)
| -1\(\frac{17}{19}\) | |
| 1\(\frac{13}{15}\) | |
| -1\(\frac{1}{26}\) | |
| \(\frac{5}{29}\) |
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.
9z + 9 = \( \frac{z}{3} \)
3 x (9z + 9) = z
(3 x 9z) + (3 x 9) = z
27z + 27 = z
27z + 27 - z = 0
27z - z = -27
26z = -27
z = \( \frac{-27}{26} \)
z = -1\(\frac{1}{26}\)
