Lol I'll just comment to get 5 points
Answer:
a) 
b) 
c) term number 17 is the one that gives a value of 40
Step-by-step explanation:
a)
The sequence seems to be arithmetic, and with common difference d = 3.
Notice that when you add 3 units to the first term (-80, you get :
-8 + 3 = -5
and then -5 + 3 = -2 which is the third term.
Then, we can use the general form for the nth term of an arithmetic sequence to find its simplified form:

That in our case would give:

b)
Therefore, the term number 20 can be calculated from it:

c) in order to find which term renders 20, we use the general form we found in step a):

so term number 17 is the one that renders a value of 40

Answer:
√3, and -√3
Step-by-step explanation:
to find the zeros or roots of the polinomial x²-3 make it equal to zero and solve for x
x²-3=0 add 3 to both sides to isolate x
x² = 3 squareroot both sides
√x²= √3
x= ±√3 are the two zeros
Oh my gosh I used to have that same workbook I HATED it. Anyways, the formular for volume is length x width x height, so for this rectangular prism you would multiply 4 2/5 x 10 x 3. Also it doesn’t matter which order you multiply because you should still have the same end result.
Hope this helps! If you need anymore answers from this book then ask me. My teacher made us do like 10 pages a day all school year.
