Its 60 because l*w*h so 4*5*3=60
Mulitpilicty is how many times a root repeats
factor
factor x first
x(2x^2+x-1)
using math
(x)(x+1)(2x-1)
no roots repeat
if it is equal to 0 then the roots are
0 multiplicty 1
-1 multiplicty 1
1/2 multiplicty 1
You simply substitute and then solve.
Exp, at x=2, 3(2)+y=15, y=15-6=9
so the values, from left to right are;
9, 4, -3, 15, 6, 5, 1
If we put the numbers in order, it would be 12, 12.50, 13, 18.50, 20, 20 we can see the middle numbers would be 13 and 18.50. if only one number is wanted as the median, then we can do (13+18.50) divided by 2 and get 15.75.
So first divide by 10 to get 32.2 then multiply by the remaining which is 3/10 so 3. 32.2 times 3 is 96.9 round up 97 add to 322 to get 419.
