What is the area of a triangle with base 10 cm and height 6 cm?
Answer: 30 cm²
Area = (1/2) × base × height = 0.5 × 10 × 6 = 30 cm².
Which value of x makes the equation 5x − 10 = 2x + 8 true?
Answer: x = 6
3x = 18; x = 6.
A rectangle has a perimeter of 36 cm and a width of 8 cm. What is its length?
Answer: 10 cm
Perimeter = 2(l + w); 36 = 2(l + 8); l + 8 = 18; l = 10 cm.
Which table of values represents a linear relationship?
Answer: x: 1,2,3; y: 3,5,7
In x: 1,2,3; y: 3,5,7, y increases by 2 for every 1-unit increase in x, showing a constant rate (linear).
Solve: (x/4) + 3 = 7
Answer: x = 16
x/4 = 4; x = 16.
The volume of a rectangular box is 120 cm³. If the length is 5 cm and width is 4 cm, what is the height?
Answer: 6 cm
Volume = l × w × h; 120 = 5 × 4 × h; h = 120/20 = 6 cm.
