Factor completely. -5 x2y + 10 xy - 15 xy2

I need help.

Step-by-step explanation:

Always proceed by first extracting all common factors to all terms:

Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:

Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
