Area = base * height = 10 * 6 = 60 cm².

Area = length * width = 8 * 3 = 24 cm².

Area = side² = 4² = 16 cm².

Area = 1/2 * (base1 + base2) * height = 1/2 * (6 + 10) * 4 = 32 cm².

Area = 1/2 * base * height = 1/2 * 10 * 5 = 25 cm².

The total sales for Product A over 4 quarters is $4000, so the average is $1000.

Circumference = 2 * π * radius = 2 * π * 7 = 14π cm.

The cube of -3 is -3 * -3 * -3 = -27.

The cube of 5 is calculated as 5 * 5 * 5 = 125.

The cube root of 1,000,000 is 100, since 100 * 100 * 100 = 1,000,000.

The cube root of 64 is 4, since 4 * 4 * 4 = 64.

To find the difference, convert 1/5 to a common denominator of 10: 1/5 = 2/10. So, 7/10 - 2/10 = 5/10 = 1/2.

Distance = √((7-3)² + (1-4)²) = √(4 + 9) = √13.

The LCM of 12 and 15 is 60, as 60 is the smallest number that both 12 and 15 divide evenly into.

Using Pythagorean theorem: hypotenuse = √(3² + 4²) = √(9 + 16) = √25 = 5 cm.

Each interior angle = (n-2) * 180° / n = (6-2) * 180° / 6 = 120°.

A tree with n vertices has exactly n-1 edges. For 7 vertices, it requires 7-1 = 6 edges.

Perimeter = 2 * (length + width) = 2 * (8 + 4) = 24 cm.

Perimeter = 6 * side = 6 * 3 = 18 cm.

Perimeter = 4 * side = 4 * 6 = 24 cm.

To find the product of 2/3 and 3/4, multiply the numerators and the denominators: (2*3)/(3*4) = 6/12 = 1/2.

The first 4 even numbers are 2, 4, 6, and 8. Their product is 2 * 4 * 6 * 8 = 384.

The reciprocal of a fraction is obtained by flipping the numerator and denominator. Thus, the reciprocal of 4/5 is 5/4.

Distributing gives 3x + 12 - 2x + 2 = x + 14.

Distributing gives 2x + 6 + 3x - 3 = 5x + 3.

Subtract 2x from both sides: 2x + 1 = 9. Subtract 1: 2x = 8. Divide by 2: x = 4.

The square of 12 is calculated as 12 * 12 = 144.

The square of 15 is 15 * 15 = 225.

The square of 20 is 20 * 20 = 400.

The square of 8 is 8 * 8 = 64.
