The answer to this question is B
Answer:
since her score was -12 from being perfect
if she had scored 12 more points her score would have been perfect .
that is difference between her score and the perfect score o each quiz was <u>12</u>
The terms appear to increase by a multiple of -2. The first 7 terms are:
-4 + 8 + -16 + 32 + -64 + 128 + -256. Add these together.
The sum of these numbers is -172.
Answer:
A
Step-by-step explanation:
Since x is along the entire parallelogram we will use cosine to figure out it's length.
First we do cos(40) and get cos(40)=.7660
This .7660 is equal to 
or 
So we do .7660*4 and get 3.064 in for x
A is the only option with x=3.06 so it is the correct answer
Answer:
16a^2 + 4a or 4a(4a+1)
Step-by-step explanation:
Use the distributive property (or FOIL).
First, the 3a2 becomes 6a.
6a x 4a = 24a^2
4a x -2a = 8a^2
4a x 1 = 4a
Simplify.
24a^2 - 8a^2 + 4a
=16a^2 + 4a
Other options:
=16a^2 + 4a
=4a(4a+1)
Hope this helped.
