Every answer below was worked out and checked by the MathPlug maths engine. Tap to see the steps.
Question 1
What is 12 + 13?
- A25
- B26
- C1
- D56
Show answer and working
Step 1: Find a common denominator
The LCM of 2 and 3 is 6.
Why? We need both fractions cut into parts of the same size before we can add them.
Step 2: Rewrite each fraction
12 = 36 (× 3 top and bottom)
13 = 26 (× 2 top and bottom)
Step 3: Add the numerators
36 + 26 = 56
Final answer: 56
Question 2
If x = −2 and y = 5, evaluate 2x2 − 5y.
- A−9
- B−17
- C33
- D−33
Show answer and working
Step 1: Substitute
2x2 − 5y = 2 × (−2)2 − 5 × 5
Step 2: Powers first
= 2 × 4 − 5 × 5
Step 3: Then multiply and subtract
= 8 − 25 = −17
Final answer: −17
Question 3
The parallel sides of a trapezium are 11 cm and 16 cm, and the distance between them is 12 cm. Find its area.
- A162 cm²
- B324 cm²
- C174 cm²
- D2,112 cm²
Show answer and working
Step 1: Use ½(a + b)h
½ × (11 + 16) × 12 = ½ × 27 × 12 = 162 cm²
Final answer: 162 cm²
