A(n) __________ is two expressions separated by an equal sign.
expression |
|
formula |
|
problem |
|
equation |
An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
Which types of triangles will always have at least two sides of equal length?
equilateral and isosceles |
|
equilateral, isosceles and right |
|
equilateral and right |
|
isosceles and right |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
If side x = 11cm, side y = 10cm, and side z = 13cm what is the perimeter of this triangle?
| 34cm | |
| 28cm | |
| 36cm | |
| 27cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 11cm + 10cm + 13cm = 34cm
A(n) __________ is to a parallelogram as a square is to a rectangle.
quadrilateral |
|
rhombus |
|
trapezoid |

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) = 6, length (l) = 4, and width (w) = 3. What is the volume?
| 48 | |
| 36 | |
| 72 | |
| 243 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 4 x 3
v = 72
