I'm not good with intigers, but if you added two negative intigers together wouldn't it still be negative? If you added -1 to -2 you'd get -3. It would always be less than the two original integers.
In this equation, you have to treat the number in the bracket first on the basis of BODMAS
15 - [-3]- 4
Note that when two minuses come together the product is a plus sign.
15 +3 - 4
You have to add before you subract
18 - 4 =14
Therefore, 15- [-3] - 4 = 14.
V o = 15 m/s, a = 2 m/s², t = 15 s
v = v o + a · t
v = 15 m/s + 2 m/s² · 15 s = 15 m/s + 30 m/s = 45 m/s
Answer: A ) 45 m/s
Answer:
x^3 + 3x^2 + 2x = x(x^2 + 3x + 2)
= x(x^2 + x + 2x + 2)
= x(x(x+1) + 2(x+1))
=x(x+1)(x+2)
Hope this helps!
