Use the Pythagorean Theorem: a^2 + b^2 = c^2. a and b are the legs, and c is the hypotenuse. Plug in your numbers: 9^2 + b^2 = 12^2
81 + b^2 = 144. Subtract 81 from 144 : b^2 = 63. Now take the square root of 63, which is 7.9. 7.9 ft is your answer.
3rd one.
6(x + 2) is simply 6x + 12
Do 12 + 7
You will get 19.
Now put that together.
6x + 19, which is option 3
Hope this helped! :D
Answer:
b. How to interpret collected data.
Step-by-step explanation:
It should be 20 if I’m right
ANSWER
The correct answer is C.
EXPLANATION
The given polynomial has equation

According to the Remainnder Theorem, if (b+4) is a factor of p(b) = b³+3b²-b+12 then

We now substitute b=-4 to check.


Simplify:

Since p(-4) is zero, (b+4) is a factor of p(b) = b³+3b²-b+12.
The correct choice is C.
