Answer:
First, third, and fourth one would be the answers.
To simplify by distribution we proceed as follows;
7a(3b-2c+4)
=7a*3b-2c*7a+4*7a
=21ab-14cb+28a
the answer is:
21ab-14cb+28a
9514 1404 393
Answer:
irrational numbers
Step-by-step explanation:
The real numbers whose decimals do not end and do not repeat are irrational numbers.
__
If a decimal number ends or repeats, it can be represented by the <em>ratio</em> of two integers. That is the essence of a <em>ratio</em>nal number.
Answer:
the y intercept is (0,29)
Answer: 
Step-by-step explanation:
For it to bisect the segment, we need to find the midpoint.
The midpoint is 
Now, for it to be perpendicular, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.
The slope of the given segment is 
, so the slope of the perpendicular bisector is 
Thus, the equation of the line in point-slope form is
