Which of the following statements about math operations is incorrect?

70% Answer Correctly

	you can subtract monomials that have the same variable and the same exponent
	all of these statements are correct
	you can add monomials that have the same variable and the same exponent
	you can multiply monomials that have different variables and different exponents

Solution

You can only add or subtract monomials that have the same variable and the same exponent. For example, 2a + 4a = 6a and 4a² - a² = 3a² but 2a + 4b and 7a - 3b cannot be combined. However, you can multiply and divide monomials with unlike terms. For example, 2a x 6b = 12ab.

A trapezoid is a quadrilateral with one set of __________ sides.

70% Answer Correctly

	equal length
	parallel
	right angle
	equal angle

Solution

A trapezoid is a quadrilateral with one set of parallel sides.

To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?

83% Answer Correctly

	Inside
	Odd
	Last
	First

Solution

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.

Which of the following statements about a parallelogram is not true?

50% Answer Correctly

	a parallelogram is a quadrilateral
	the area of a parallelogram is base x height
	the perimeter of a parallelogram is the sum of the lengths of all sides
	opposite sides and adjacent angles are equal

Solution

A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).

A cylinder with a radius (r) and a height (h) has a surface area of:

53% Answer Correctly

	π r²h
	π r²h²
	4π r²
	2(π r²) + 2π rh

Solution

A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r²h and the surface area is 2(π r²) + 2π rh.
