What is the square root of 25?

The square root of 25 is 5.

Simplify the expression: 3/4 + 2/3.

To simplify the expression 3/4 + 2/3, we need to find a common denominator, which in this case is 12. Then, we convert the fractions to have the common denominator and add them together. The simplified result is 17/12.

Expand and simplify: (x + 2)(x - 1).

To expand and simplify the expression (x + 2)(x - 1), you multiply each term in the first set of parentheses by each term in the second set of parentheses. This results in x^2 + 2x - x - 2, which simplifies to x^2 + x - 2.

Calculate the area of a rectangle with length 5 cm and width 8 cm.

To calculate the area of a rectangle, you multiply the length by the width. In this case, the length is 5 cm and the width is 8 cm. Therefore, the area of the rectangle is 5 cm x 8 cm = 40 square cm.

Solve the equation: 2x + 5 = 15.

To solve the equation 2x + 5 = 15, we first subtract 5 from both sides to isolate the term with x. This gives us 2x = 10. Then, we divide both sides by 2 to solve for x, which gives us x = 5. Therefore, the solution to the equation is x = 5.

Convert 2.5 kilograms to grams.

2.5 kilograms is equal to 2500 grams.

Find the perimeter of a triangle with sides measuring 7 cm, 9 cm, and 12 cm.

The perimeter of the triangle is found by adding the lengths of all three sides. Therefore, the perimeter of the triangle with sides measuring 7 cm, 9 cm, and 12 cm is 7 + 9 + 12 = 28 cm.

Solve the proportion: 6/10 = x/20.

To solve the proportion, cross multiply to get 10x = 6 * 20, which simplifies to 10x = 120. Then divide by 10 on both sides, x = 12. Therefore, the solution to the proportion 6/10 = x/20 is x = 12.

If a train travels 240 km in 3 hours, what is its average speed in km/h?

The average speed of the train is 80 km/h. This is calculated by dividing the total distance traveled (240 km) by the total time taken (3 hours).

Find the volume of a cube with side length 4 cm.

The volume of a cube is calculated by cubing the length of one of its sides. Therefore, the volume of a cube with a side length of 4 cm is 64 cubic centimeters (4 cm x 4 cm x 4 cm = 64 cm³).
