If f(x) = x2 + x, find f(-3). A. -12 B. 3 C. 6

I believe that this would be (-3)²+-3. A negative times a negative is always positive, so -3² would be 9-3. We don't need the + sign because we would still subtract three from 9, which gives you 6. The answer would be C.

-3 squared is 9. 9 + (-3) is 6.

Therefore, it's C

A bookkeeper bought 2,000 exercise book distributed 200 books to the student from poor economic background as donation .he sold

Andrews [41]

Books left=2000-200=1800

ATQ

$\\ \sf\longmapsto 1800x+10=0.08x$

$\\ \sf\longmapsto 1800x-0.08x=-10$

$\\ \sf\longmapsto x(1800-0.08)=-10$

$\\ \sf\longmapsto x(1799.92)=-10$

$\\ \sf\longmapsto x=|\dfrac{10}{1799.92}|$

$\\ \sf\longmapsto x=0.005$

Now

$\\ \sf\longmapsto CP=0.005(2000)=10$
