What is the value of 3x + 2y when x = 4 and y = 5?

Substitute x = 4 and y = 5 into the expression 3x + 2y to get 3(4) + 2(5) = 12 + 10 = 22. Therefore, the value of 3x + 2y when x = 4 and y = 5 is 22.

Solve the equation 2(x + 3) = 14 for x.

To solve the equation 2(x + 3) = 14 for x, we first distribute the 2 to both terms inside the parentheses to get 2x + 6 = 14. Next, subtract 6 from both sides of the equation to isolate the x term, giving us 2x = 8. Finally, divide both sides by 2 to solve for x, and we find that x = 4.

Find the area of a triangle with base 10 cm and height 12 cm.

The area of a triangle is calculated by multiplying the base by the height and dividing the result by 2. In this case, the area of the triangle is (10 cm * 12 cm) / 2 = 60 square centimeters.

Simplify the expression (3x - 2y)^2.

To simplify the expression (3x - 2y)^2, we need to expand it using the formula (a - b)^2 = a^2 - 2ab + b^2. Applying this formula, we get (3x)^2 - 2*(3x)*(2y) + (2y)^2, which simplifies to 9x^2 - 12xy + 4y^2. Therefore, the simplified expression is 9x^2 - 12xy + 4y^2.

Solve the system of equations: 2x + 3y = 8 and 4x - 3y = 2.

By adding the two equations together, we can eliminate the y variable. This gives us 6x = 10, which simplifies to x = 10/6 = 5/3. Substituting this value back into the first equation, we get 2*(5/3) + 3y = 8, which simplifies to 10/3 + 3y = 24/3, or 3y = 14/3, and y = 14/9. Therefore, the solution to the system of equations is x = 5/3 and y = 14/9.

Find the perimeter of a rectangle with length 8 cm and width 5 cm.

To find the perimeter of a rectangle, you can use the formula 2(length + width). In this case, the length is 8 cm and the width is 5 cm. Plugging these values into the formula, the perimeter is 2(8 + 5) = 2(13) = 26 cm. Therefore, the perimeter of the rectangle is 26 cm.

Calculate the slope of the line passing through the points (2, 5) and (5, 8).

The slope of the line passing through the points (2, 5) and (5, 8) is: (8 - 5) / (5 - 2) = 3 / 3 = 1.

Evaluate the expression 4x - 3y, given x = 2 and y = 3.

Substitute x = 2 and y = 3 into the expression 4x - 3y: 4(2) - 3(3) = 8 - 9 = -1. Therefore, the value of the expression 4x - 3y when x = 2 and y = 3 is -1.

Determine the volume of a rectangular prism with length 6 cm, width 3 cm, and height 4 cm.

To determine the volume of the rectangular prism, you multiply the length, width, and height. In this case, the volume would be 6 cm x 3 cm x 4 cm = 72 cubic centimeters.

Solve the inequality 2x + 5 > 13 for x.

To solve the inequality 2x + 5 > 13 for x, first subtract 5 from both sides to get 2x > 8. Then, divide by 2 to isolate x, giving x > 4. Therefore, the solution for x in the given inequality is x > 4.
