An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
If c = -5 and x = 8, what is the value of -3c(c - x)?
| 6 | |
| -195 | |
| 144 | |
| -352 |
To solve this equation, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
-3c(c - x)
-3(-5)(-5 - 8)
-3(-5)(-13)
(15)(-13)
-195
If the base of this triangle is 6 and the height is 8, what is the area?
| 22\(\frac{1}{2}\) | |
| 38\(\frac{1}{2}\) | |
| 58\(\frac{1}{2}\) | |
| 24 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 6 x 8 = \( \frac{48}{2} \) = 24
The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
h x l x w |
|
h2 x l2 x w2 |
|
lw x wh + lh |
|
2lw x 2wh + 2lh |
A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Inside |
|
Odd |
|
First |
|
Last |
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.
