-2n-h(4rx-6s)-3rx+3s i need help doing this problem

Answers

Answer 1
Answer: Ok, first step is to distribute the h to get rid of parenthesis:

-2n - 4hrx + 6hs -3rx +3s

Then you would combine like terms, but there are none! So that's your answer.
Answer 2
Answer:

- 2n - h(4rx - 6s) - 3rx + 3s =

= - 2n - h×4rx - h×(- 6s) - 3rx + 3s

= - 2n - 4hrx + 6hs - 3rx + 3s

= 2(3hs - 2hrx - 2) - 3(rx - s)

When b=0 ,

When a=3 ,

When a=6 ,

i.e. Possible solutions for (a,b) = (0,6), (9,0) , (3,4) , (6,2) .

⇒Number of possible solutions for (a,b) =4

Thus , the number of different ways can Roberto display his figure =4
