105 inches in 210 weeks, because 50/100 equals 1/2 so 210 times 1/2 equals 105.
That is a simple polynomial addition:
(7w3-4w+3)+(5w3-3w-3)
= <span>(7w^3 - 4w + 3) + (5w^3 - 3w - 3)
= </span>7w^3 - 4w + 3 + 5w^3 - 3w - <span>3
= 12w^3 - 7w
= w(</span><span>12w^2 - 7</span>)
16 because the neg next to the subtraction sign becomes positive then you’re just adding 14+2.
I have a feeling that it’s 56 because a lot of trash is being thrown
