$58.80 you need to multiply 2.80 x 21 to get your answer
Because she spinner it going on the right every time
You have to find how many times 40 (the denominator) goes into 120 (attempts). That's 3, so you take the numerator (17) and multiply it by that same number. And 17 times 3 is 51.
Check the picture below.
so we really have 2 equal triangles with 3 rectangles, so let's get the area of each and sum them up.

Answer:
B. 
Step-by-step explanation:
The given quadratic trinomial is;

Comparing this to
, we have a=5,b=17,c=6.

Two factors of 30 that add up to 17 is 15 and 2.
We split the middle term to obtain;

We factor by grouping;

Factor further

The correct answer is B.
