Answer:
Both C and D are factors of the binomial above.
Step-by-step explanation:
In order to find this, note that the original is difference of two squares. In order to find the binomials that come from this, you simply need to take the square root of the first and the second term.
√81x^2 = 9x
√36 = 6
Now that we have this, we can stick them in parenthesis together with alternating signs.
(9x - 6)(9x + 6)
Answer:
45%
Step-by-step explanation:
Running speed= 9mph
Biking speed= 20mph
9/20=45%
In 2008, up to 405 messages could be sent without spending more than $ 100.
Since in 2008, text messages were charged per text, and some carriers charged $59 for a basic text package of 200 texts and 20 cents per text after that, while today, most packages include unlimited text and data but cost closer to $ 100 a month, to determine the range of text messages you can send with the 2008 plan without spending more than $100, the following calculation must be performed:
- (41 / 0.2) + 200 = X
- 205 + 200 = X
- 405 = X
Thus, in 2008, up to 405 messages could be sent without spending more than $ 100.

The area of one face of the cube is 144cm2
Answer:
No
Step-by-step explanation:
Using the converse of Pythagoras' identity.
If the longest side squared is equal to the sum of the squares of the other 2 sides then the triangle is right.
The longest side = 61, thus
61² = 3721
12² + 60² = 144 + 3600 = 3744 ≠ 3721
Thus these sides do not form a right triangle.
