Let's see....    put in 5 for x   and  - 1 for  y    

-1 = 2 (5) - 11     ?    WHat do you think?    True or false?

1>  Well, yo would just add the x^3 tems in the two fxns   1 + 5 = 6

2>  If a is a constant, it will only change the coefficients of the functions, not the degree of the terms

          so the greatest degree will still be 4    form   the x^4  and 2x^4 in the two fxns

3>  Similar to 2   except the lowest degree will be  1    from the 2x   term

4>    not sure

            the constant will be 47    

5>   when the two functions are multiplied you will have a x^4 * 2x^4    = 2 x^8 term in the final answer....    dgree 8

Per cents are always kinda tricky

150% of 2  == 3    2nd side length

150% 0f 3  = 4.5

150% 0f 4.5 = 6.75

z% of 2 = 6.75

6.75/2 = 3.375           337.5%  OF 2      The INCREASE FROM 2    (6.75-2)/2 = 2.375 = 237.5 %

SO I think the wording is tricky, but the answer looked for is 237.5 %

You are given   LB   and  BAG     and you want   LB/BAG

11/3 LB  /  4/9 BAG  = 11/3  * 9/4  = 99/12  LB/BAG = 8 1/4  LB / BAG

Here is a Desmos graphical solution, which might help to find the algebraic solution....which I think might be kind of messy,,,,,,

I think I'll think some more about this one!   Hmmmmmm ....

This will produce a cone   one leg will be the height ...the other will be the radius

Volume of a cone = pi r^2 h/3     r^2 is more determining factor of final volume than h....  you can see that the larger radius ^2    will produce the larger cone  ....rotate around the 3 leg (h)

pi 4^2  3 /3 = 16 pi =~50 cm³
