As Col08 said, we cannot see the options, but if they are getting at which is the better deal, the 14 oz blueberries for $4.20 is better.
Answer:
1) +1,+2,+3,+6,-1,-2,-3,-6
2) f(2) = 0
3) (x+1)(x-2)(x-3)
4) x=-1, x=2, x=3
Step-by-step explanation:
For explanation, see the attached files
The area of a trapezoid is found using the formula, A = ½ (a + b) h, where 'a' and 'b' are the bases (parallel sides) and 'h' is the height (the perpendicular distance between the bases) of the trapezoid.
We are given that 0<a<b, which means that 0>-a>-b if you multiply it by -1, which means what's given by our inequality is true and we are done.
Yes, 60° is right.
Do you need me to explain why?
