What is the volume of a rectangular prism that has a length of 5cm, width of 4cm, and height of 7cm?

Solution: 140cm^3 When finding the volume of a rectangular prism, you have to use the formula: l*w*h. When the numbers given in the question are plugged into that formula (5*4*7), you will get an answer of 140;

### Subject: Basic Math

Solve the following equation using PEMDAS. 5+3^2-(10+3)+5x2=?

Solution: 11 When uing PEMDAS, the problem should be solved in the given order. The first letter, P, stands for parenthesis. That means that the numbers in parenthesis should be solved first (10+3). The next letter, E, stands for Exponents (3^2). After solving the two smaller equations, the problem would be shown as 5+9-13+5x2. The following letters, MDAS, mean that the remaining problem should be solved in order of Multiplication, Division, Addition, then, Subtraction. After following these steps, you are given the answer of 11.

### Subject: Algebra

Write an equation of the line with the slope 5 and a y-intercept of (0, -8).

y=5x-8 Because the slope and the y-intercept are already given, it is shown that the equation will be in slope-intercept form (y=mx+b). The numbers would then be plugged into the equation to find the solution to the problem.
