Now you need to find two numbers that multiply to 48 and add to Those numbers are 4 and Solve for x. To solve such problems, move all the terms with an unknown to one side of the equal sign and the numbers to the other. Solve for the two unknowns. Set each equation equal to zero. Next, arrange one of the equations so that when it is subtracted from or added to the other equation, one of the terms becomes zero and drops out of the equation. Next, solve for the remaining unknown. To divide numbers with exponents, subtract the exponents.
In this problem, subtract the 4 from the 12, leaving x 8 as the correct answer. Solve for y. Set the equation to equal zero: Q To divide fractions, invert the second term and multiply. The cube root is the number that, when multiplied by itself three times, results in the answer. It would be wise to memorize all the cubes from 2 to 10, just to prepare for ASVAB test item possibilities. Isolate the variable of interest on one side of the equation.
In this problem, you must multiply each side by h, leaving g on the left side of the equation and h on the right side. Which of the following is an equilateral triangle? An equilateral triangle has three equal sides and angles, so D is the correct answer. What is the perimeter of the following rectangle? To find the perimeter of a quadrilateral, add the lengths of the four sides.
What is the circumference of the following circle? The figure gives the radius, which is one-half the length of the diameter. To find the diameter, multiply the radius by 2. In this problem, the diameter is 8 meters. An equilateral triangle has three equal angles. In the following right triangle, what is the length of side AB? What is the area of the following triangle?
This is a right triangle, so 4 ft is the height of the triangle and 8 ft is the base. What is the diameter of the following circle? The diameter is 2r. What is the volume of a cylinder with a height of 15 m and a radius of 5 m? View Correct Answer. Answer: B Isolate the unknown on one side. For grades 3, 4, and 5.
