For this case what you should do is:
1) Multiplication of terms within parentheses correctly.
2) Rewrite the expression respecting power properties.
3) Add or subtract terms of equal power.
Note: See attached image.
Answer:
x ^ 3 + 3x ^ 2 -16x - 48 = 0
Answer:
2 units
Step-by-step explanation:
The radius of the circle is 2 units because you can find the radius by multiplying the diameter by 2. The radius is half of the diameter.
4 divided by 2 is 2.
Hope this helped :)
Answer: 
Step-by-step explanation:
Pythagorean theorem:
, where a and b are the legs and c is the hypotenuse.
We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.


Since we don't know what
is, we're going to isolate it by subtracting 81 on both sides

We have to square root both sides in order to find out b (or x in the problem).

When you put this on a calculator it would result in
which is the answer d in the problem.
Answer: t is less than or equal to 7.
Step-by-step explanation:
6t - 3 is less than or equal to 39.
Add 3 to both sides.
6t is less than or equal to 42.
Divide by 6.
t is less than or equal to 7.
Answer:
45
Step-by-step explanation:
45 is constant, because no mater how many miles you drive, you will always be charged $45. It stays the same
