A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
rhombus |
|
triangle |
|
quadrilateral |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Simplify 7a x 9b.
| 63a2b2 | |
| 63\( \frac{b}{a} \) | |
| 63ab | |
| 16ab |
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 x 9b = (7 x 9) (a x b) = 63ab

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
If side x = 8cm, side y = 14cm, and side z = 13cm what is the perimeter of this triangle?
| 35cm | |
| 33cm | |
| 27cm | |
| 25cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 8cm + 14cm + 13cm = 35cm
Which of the following statements about math operations is incorrect?
you can subtract monomials that have the same variable and the same exponent |
|
all of these statements are correct |
|
you can add monomials that have the same variable and the same exponent |
|
you can multiply monomials that have different variables and different exponents |
You can only add or subtract monomials that have the same variable and the same exponent. For example, 2a + 4a = 6a and 4a2 - a2 = 3a2 but 2a + 4b and 7a - 3b cannot be combined. However, you can multiply and divide monomials with unlike terms. For example, 2a x 6b = 12ab.
