Answer:
The plan A lasts 1.25 hours and plan B lasts 0.5 hours.
Step-by-step explanation:
Let the plan A takes x hours for training and plan B takes y hours for training.
So, from the conditions given we can write two different equations as
4x + 8y = 9 ............ (1) and
2x + 3y = 4 ............. (2)
Now. solving equations (1) and (2) we get,
8y - 6y = 9 - 8
⇒ 2y = 1
⇒ y = 0.5 hours.
Now, from equation (2) we get,
2x = 4 - 3 × 0.5 = 2.5
⇒ x = 1.25 hours.
Therefore, plan A lasts 1.25 hours and plan B lasts 0.5 hours. (Answer)

Answer:
2x^4 - 9x^3 -8x^2 + 15x
Step-by-step explanation:
(x^2-5x)(2x^2+x-3) distribute first
2x^4
x^2 + x = x^3
5 * 2x^2 x= 10x^3
5x^1+1 = 5x^2
5 * 3x = 15x Put them all together
2x^4 + x^3 - 3x^2 - 10x^3 - 5x^2 + 15x Like terms
2x^4 + x^3 -10x^3 - 3x^2- 5x^2 + 15x Add similar terms
= 2x^4 + x^3 - 10x^3 - 8x^2 + 15x more adding terms
2x^4 - 9x^3 -8x^2 + 15x

I am taking my first programming course, so my apologies if this is a dumb question/possibly classified by the wrong category on this site. One of the exercise problems I am working on is the following:
Define a function print_total_inches, with parameters num_feet and num_inches, that prints the total number of inches. Note: There are 12 inches in a foot. Ex:
print_total_inches(5, 8) prints:
Total inches: 68
