Answer:
-25
Step-by-step explanation:
if you are multiplying x by -2/5 you have to divide each side by it to get
x = 10 ÷ -2/5
and if you change it to (10/1)/(-2/5)
=(10/1) • -5/2
and whene you multiply them you get -50/2
which is -25/1 or -25
14/27. I have linked my working our down below make sure to have a look at it for a better understanding.
W^2 + w - 20 = (w + 5)(w - 4)
(w - 3) (w - 4) w^2 - 7w + 12
---------- * -------- = ------------------
(w + 5) (w - 4) w^2 + w - 20
