What is 8a4 - 6a4?

73% Answer Correctly
14
2
48a4
2a4
Solution

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

8a4 - 6a4 = 2a4

2

If BD = 21 and AD = 22, AB = ?

76% Answer Correctly
12
1
2
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 = 22 - 21
AB = 1

3

If side a = 1, side b = 4, what is the length of the hypotenuse of this right triangle?

64% Answer Correctly
\( \sqrt{145} \)
\( \sqrt{80} \)
\( \sqrt{17} \)
5
Solution

According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:

c2 = a2 + b2
c2 = 12 + 42
c2 = 1 + 16
c2 = 17
c = \( \sqrt{17} \)

4

If a = c = 8, b = d = 9, what is the area of this rectangle?

80% Answer Correctly
72
9
3
7
Solution

The area of a rectangle is equal to its length x width:

a = l x w
a = a x b
a = 8 x 9
a = 72

5
