Simplify 5a x 8b.
| 40ab | |
| 13ab | |
| 40a2b2 | |
| 40\( \frac{b}{a} \) |
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 8b = (5 x 8) (a x b) = 40ab

equal angle |
|
parallel |
|
right angle |
|
equal length |
A trapezoid is a quadrilateral with one set of parallel sides.
Solve -5c + 2c = 6c - 6y - 5 for c in terms of y.
| \(\frac{8}{11}\)y + \(\frac{5}{11}\) | |
| -3\(\frac{3}{4}\)y - 1\(\frac{3}{4}\) | |
| y + \(\frac{1}{5}\) | |
| 2y + 4\(\frac{1}{2}\) |
To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.
-5c + 2y = 6c - 6y - 5
-5c = 6c - 6y - 5 - 2y
-5c - 6c = -6y - 5 - 2y
-11c = -8y - 5
c = \( \frac{-8y - 5}{-11} \)
c = \( \frac{-8y}{-11} \) + \( \frac{-5}{-11} \)
c = \(\frac{8}{11}\)y + \(\frac{5}{11}\)
The dimensions of this cube are height (h) = 1, length (l) = 3, and width (w) = 3. What is the volume?
| 9 | |
| 42 | |
| 384 | |
| 24 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 3 x 3
v = 9
On this circle, a line segment connecting point A to point D is called:
circumference |
|
diameter |
|
radius |
|
chord |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
