What is the value of x in the equation 3x + 5 = 17?

The value of x in the equation 3x + 5 = 17 is x = 4.

Simplify the expression 4x² - 2x + 8x² - 3x.

The simplified expression is 12x² - 5x.

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

To find the area of a rectangle, you can multiply its length by its width. In this case, multiplying the length of 8 cm by the width of 5 cm gives you an area of 40 square cm for the rectangle.

Solve the equation 2(x - 3) = 4x + 5.

To solve the equation 2(x - 3) = 4x + 5, first distribute the 2 on the left side to get 2x - 6 = 4x + 5. Next, isolate x by subtracting 2x from both sides to get -6 = 2x + 5. Then, subtract 5 from both sides to get -11 = 2x. Finally, divide by 2 to find x = -11/2 or x = -5.5.

Find the slope of a line passing through the points (2, 4) and (-3, 7).

The slope of a line passing through the points (2, 4) and (-3, 7) can be calculated using the slope formula: \( m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \), where (x1, y1) = (2, 4) and (x2, y2) = (-3, 7). Substituting these values in, we get \( m = \frac{7 - 4}{-3 - 2} = \frac{3}{-5} = -\frac{3}{5} \). Therefore, the slope of the line passing through these two points is -3/5.

Convert the mixed number 3 1/4 into an improper fraction.

To convert the mixed number 3 1/4 into an improper fraction, we multiply the whole number (3) by the denominator of the fraction (4) and add the numerator (1) to get the new numerator. This gives us (3*4) + 1 = 12 + 1 = 13. So, the improper fraction is 13/4.

Solve for y in the equation 3y - 7 = 2(y + 4).

To solve for y in the equation 3y - 7 = 2(y + 4), first distribute 2 to y and 4: 3y - 7 = 2y + 8. Next, isolate y by moving 2y to the left side: 3y - 2y = 8 + 7. Simplifying gives y = 15.

Find the volume of a cylinder with radius 4 cm and height 10 cm.

The volume of a cylinder can be calculated using the formula V = ?r²h, where r is the radius and h is the height. Substituting the values, we get V = ?(4)²(10) = 160? cubic cm. Hence, the volume of the cylinder is 160? cubic cm or approximately 502.65 cubic cm when rounded to two decimal places.

Simplify the expression (2x + 3)².

The expression (2x + 3)² simplifies to 4x² + 12x + 9.

Calculate the perimeter of a triangle with sides measuring 5 cm, 7 cm, and 9 cm.

The perimeter of a triangle is calculated by adding the lengths of all three sides. In this case, the perimeter of the triangle with sides measuring 5 cm, 7 cm, and 9 cm would be 5 cm + 7 cm + 9 cm = 21 cm.
