Answer:
20x⁵ + 20x⁴
Step-by-step explanation:
Use distributive rule: a*(b +c) =a*b + a*c
5x⁴(4x + 5) = 5x⁴ * 4x + 5x⁴ * 5
= 20x⁵ + 20x⁴
Hint: 5x⁴ * 4x multiply the coefficient and then the variables. For multiplying variable, if they two have same base, then add the powers
5*4 * x⁴ * x = 20x⁵
-We cannot add 32 to both sides yet since it is attached to F within the parenthesis.
-It is not subtract F from both sides since the F is already separated on the opposite side from C.
-We cannot divide F because it is still within the parenthesis.
I assume by 5959 you mean 5/9 and by 9595 you mean 9/5. So by multiplying
each side by 9/5, you are able to isolate the parenthesis (F-32).
9/5C= F-32
If you wanted to solve the equation all the way through, you would just add 32 to each side.

The fish box is 6 * 6 * 4 = 144 cubic square inches
144 = one box so divide 3456 by 144 to see how many boxes will go into the aquarium
3456 / 144 = 24
24 boxes of fish food could fit in the aquarium
This is an arithmetic sequence question
The formula for the nth term of a sequence is 1+(n-1)d where a is the first term(63360), n is the 55th term, d is the common difference between consecutive terms(63368-63360)=8
Altitude on 55th step= 63360+(55-1)8
=63360+(54x8)
=63360+432
=63792 inches
