Answer:
21y^2+11.2
Step-by-step explanation:
4-3y(-7y)+7.2
combine like terms
-3y (-7y) = 21y^2
add 4 to 7.2
11.2
21y^2 + 11.2
Answer:
Edit: This is incorrect, it might actually be the 3rd answer, draw arcs on either side of a given point on the line?
Draw arcs on either side of a given point off of the line I believe.
Step-by-step explanation:
Bisect a Segment:
Step 1 - open up your compass so that it is slightly larger than the segment. Put the compass on point A on the given segment and swing an arc above and below the lines. Do the same on point B. Create the points where the circle intersects.
Step 2 - Draw a line going through the points. That’s the bisector.
Answer:
25000000
5000 X 10 is 50000
50000 X 10 is 500000
500000 X 50 is 25000000
Step-by-step explanation:
Remember that the quadratic formula is:
.
stands for the coefficient of the first term, the one associated with the
,
stands for the coefficient of the second term, the one associated with
, and
stands for the value of the constant.
In
, our a-value is 1, our b-value is also 1, and our c-value is also 1.
Thus, when we plug in our values into our formula, we get the answer:

Simplifying this answer using
, we get our final answer of:
