A(n) __________ is to a parallelogram as a square is to a rectangle.
triangle |
|
trapezoid |
|
quadrilateral |
|
rhombus |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
The dimensions of this cube are height (h) = 1, length (l) = 6, and width (w) = 3. What is the volume?
| 10 | |
| 16 | |
| 72 | |
| 18 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 6 x 3
v = 18
Find the value of c:
4c + z = 1
-3c - 7z = -5
| 1\(\frac{1}{4}\) | |
| \(\frac{2}{25}\) | |
| -1\(\frac{9}{46}\) | |
| \(\frac{1}{11}\) |
You need to find the value of c so solve the first equation in terms of z:
4c + z = 1
z = 1 - 4c
then substitute the result (1 - 4c) into the second equation:
-3c - 7(1 - 4c) = -5
-3c + (-7 x 1) + (-7 x -4c) = -5
-3c - 7 + 28c = -5
-3c + 28c = -5 + 7
25c = 2
c = \( \frac{2}{25} \)
c = \(\frac{2}{25}\)

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
If a = c = 7, b = d = 8, what is the area of this rectangle?
| 8 | |
| 56 | |
| 35 | |
| 2 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 7 x 8
a = 56
