Question 1

What is the value of x in the equation 2x + 4 = 12?

Accepted Answer

x = 2

Answer

To solve the equation 2x + 4 = 12, first subtract 4 from both sides to isolate the term with x, resulting in 2x = 8. Next, divide both sides by 2 to find the value of x. This calculation yields x = 4.

Question 2

What is the perimeter of a rectangle with length 5 cm and width 3 cm?

Accepted Answer

14 cm

Answer

The perimeter of a rectangle is found by adding the lengths of all four sides, or by using the formula P = 2(length + width). For a rectangle with a length of 5 cm and a width of 3 cm, the perimeter is calculated as 2(5 cm + 3 cm). This simplifies to 2(8 cm), resulting in a perimeter of 16 cm.

Question 3

What is the area of a triangle with base 6 cm and height 4 cm?

Accepted Answer

12 cm²

Answer

The area of a triangle is calculated using the formula A = (1/2) × base × height. For a triangle with a base of 6 cm and a height of 4 cm, the area is (1/2) × 6 cm × 4 cm. This calculation results in (1/2) × 24 cm², which equals 12 cm².

Question 4

What is the value of 3²?

Accepted Answer

9

Answer

The expression 3² represents 3 raised to the power of 2, which means multiplying 3 by itself. Therefore, 3² is calculated as 3 × 3. This operation results in a value of 9.

Question 5

Which of the following is an example of a prime number?

Accepted Answer

7

Answer

A prime number is a whole number greater than 1 that has only two positive divisors: 1 and itself. Among the given options, 7 fits this definition perfectly, as its only divisors are 1 and 7. Numbers like 6, 8, and 9 have additional divisors, making them composite numbers.
