What is the volume of a rectangular prism with length 5 m, width 3 m, and height 4 m?
Answer: 60 m³
Volume = l × w × h = 5 × 3 × 4 = 60 m³.
Which expression is equivalent to x² − 9?
Answer: (x − 3)(x + 3)
x² − 9 is a difference of squares: (x − 3)(x + 3).
On a number line, which point is farthest from zero?
Answer: −8
The absolute value of −8 is 8, which is the largest among |−8|, |6|, |−5|, and |7|.
A data set is: 4, 7, 9, 4, 6, 10, 4. What is the mode?
Answer: 4
The mode is 4 because it appears three times, more than any other value.
Two lines are parallel. One line has a slope of 3. What is the slope of the other line?
Answer: 3
Parallel lines have equal slopes, so the other line also has a slope of 3.
Solve: |2x − 4| = 10
Answer: x = 7 or x = −3
2x − 4 = 10 gives x = 7, and 2x − 4 = −10 gives x = −3.
A science class recorded temperatures (°F) for one week: 68, 72, 65, 70, 73, 69, 71. What is the median temperature?
Answer: 70°F
Ordered: 65, 68, 69, 70, 71, 72, 73 — the middle (4th) value is 70°F.
