Question 1

What is the value of 3(x − 2) when x = 4?

Accepted Answer

6

Answer

To find the value of 3(x − 2) when x = 4, substitute 4 for x in the expression. First, calculate the value inside the parentheses: 4 - 2 = 2. Then, multiply this result by 3: 3 * 2 = 6. Therefore, the value of the expression is 6.

Question 2

What is the perimeter of a rectangle with length 8 cm and width 5 cm?

Accepted Answer

26 cm

Answer

The perimeter of a rectangle is calculated by adding the lengths of all four sides. The formula is P = 2 * (length + width). For a rectangle with length 8 cm and width 5 cm, the perimeter is 2 * (8 cm + 5 cm) = 2 * 13 cm = 26 cm.

Question 3

If a triangle has angles of 50° and 60°, what is the measure of the third angle?

Accepted Answer

70°

Answer

The sum of the interior angles in any triangle always equals 180 degrees. If two angles are given as 50° and 60°, their sum is 110°. To find the third angle, subtract this sum from 180°: 180° - 110° = 70°.

Question 4

What is the greatest common factor (GCF) of 18 and 24?

Accepted Answer

6

Answer

The greatest common factor (GCF) is the largest number that divides evenly into two or more numbers. The factors of 18 are 1, 2, 3, 6, 9, 18. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. The largest number common to both lists is 6.

Question 5

Which number is a prime number?

Accepted Answer

17

Answer

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Of the given options, 4 is divisible by 2, 9 by 3, and 21 by 3 and 7. Only 17 is solely divisible by 1 and 17, making it a prime number.
