you should get this in the formula
a 2 subtracting a negative 6 makes it a positive, meaning your just adding 6 plus2, to get 8
Answer:
Step-by-step explanation:
The area of a trapezoid is the average of the parallel bases times the height.
A=h(a+b)/2 and since we have two identical trapezoids the total are will be
A=h(a+b) in this case
A=15(32+25)=855mm^2
Answer:
H should be the right answer
Step-by-step explanation:
the amount of each portion together should be less than or equal to 10.5.

Explanation:
Ask yourself this: "When is the graph completely horizontally flat?" The answer to this question is when x is between -4 and -2. This is where the graph is constant. All other intervals are either increasing or decreasing.

So this is why the answer is
Note how only choice A has both endpoints in the negative region, so it is a quick way to spot the answer.
