For this case, we have initially both plants are 3 cm tall.
If a month later the plant A is 7 cm higher, it means that its height will be:

If they tell us that plant B is half the height of plant A, that means:

Answer:
5 centimeters
All so have to do is make sure to convert the negatives and positives of the second group of values since there is a subtraction symbol that you have to distribute to that section.
This would turn the expression into
3x^5 + 3x^2 - 4x^3 + x - 6 - x^3 - 4x^4 - 2x^2 + 10x
Then combine like terms and line all the values in order from greatest exponent value to least to get
3x^5 - 4x^4 - 5x^3 + x^2 +11x - 6
Hope this helped :)

Substitute the above values in 
This gives:


<em>From the list of given options, only option A uses the given form of the formula...</em>
50 miles. 15 is to 30 as 50 is to 100.
In polar coordinates, we have


From this we can write

If

, then

, so we get
