1

If AD = 23 and BD = 18, AB = ?

75% Answer Correctly
11
12
18
5

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 23 - 18
AB = 5


2

On this circle, a line segment connecting point A to point D is called:

46% Answer Correctly

circumference

diameter

chord

radius


Solution

A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).

Simplify 5a x 6b.

85% Answer Correctly
30\( \frac{b}{a} \)
30\( \frac{a}{b} \)
30a2b2
30ab

Solution

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

5a x 6b = (5 x 6) (a x b) = 30ab


4

If side x = 11cm, side y = 15cm, and side z = 8cm what is the perimeter of this triangle?

83% Answer Correctly
25cm
34cm
28cm
38cm

Solution

The perimeter of a triangle is the sum of the lengths of its sides:

p = x + y + z
p = 11cm + 15cm + 8cm = 34cm


5

Simplify (3a)(8ab) + (2a2)(2b).

65% Answer Correctly
44a2b
-20ab2
28a2b
28ab2

Solution

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

(3a)(8ab) + (2a2)(2b)
(3 x 8)(a x a x b) + (2 x 2)(a2 x b)
(24)(a1+1 x b) + (4)(a2b)
24a2b + 4a2b
28a2b
