If you factor the trinomial using the AC method the answer would be
(x-3)(x+9)
there is no inverse though
Which ever graph looks like this
A farm had 480 acres more wheat than corn. Let use "W" to represent the Wheat and let use "C" to represent the corn. Hence, we have below:
W=C+480
The farmers collected 80% of the wheat and 25% of the corn and the area of the wheat is 300 acres less than the area of the corn:
W-0.8W=C-0.25C+300
0.2W=0.75C+300
We have two equations, two unknowns:
0.2(C+480)=0.75C+300
0.2C+96=0.75C+300
0.55C=294
C=534.55
9/10 of an ounce is 0.9. 0.9 X 72 = 64.8.
There is 64.8 ounces in a box.
