Simplify 6a x 4b.
| 24\( \frac{a}{b} \) | |
| 24ab | |
| 24\( \frac{b}{a} \) | |
| 24a2b2 |
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.
6a x 4b = (6 x 4) (a x b) = 24ab
Which of the following is not true about both rectangles and squares?
all interior angles are right angles |
|
the lengths of all sides are equal |
|
the perimeter is the sum of the lengths of all four sides |
|
the area is length x width |
A rectangle is a parallelogram containing four right angles. Opposite sides (a = c, b = d) are equal and the perimeter is the sum of the lengths of all sides (a + b + c + d) or, comonly, 2 x length x width. The area of a rectangle is length x width. A square is a rectangle with four equal length sides. The perimeter of a square is 4 x length of one side (4s) and the area is the length of one side squared (s2).

If the base of this triangle is 7 and the height is 2, what is the area?
| 58\(\frac{1}{2}\) | |
| 28 | |
| 15 | |
| 7 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 7 x 2 = \( \frac{14}{2} \) = 7
