Answer: 
Step-by-step explanation:
We have the following polynomial:

This is a polynomial of the form
. Following this rule to expand it, we have:


Applying common factor
:

Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to
. Hence, the final simplification is:

Answer:
A = 46
B = 134
C = 78
Step-by-step explanation:
Step-by-step explanation:
78% of those surveyed bought popcorn statistic or parameter. This means that significantly more than half of the given population bought popcorn statistic or parameter.
If the population is, say ten thousand, then 78% of 10000 is
10000 × 78/100 = 7800.
Which is more than half the whole population.
Answer:
37 units
Step-by-step explanation:
The two points form a right triangle so
a²+b²=c² so
(8-20)²(x values)+(40-5)²(y values)=c² (distance) so
12²+35²=c² so
144+1225=c²
1369=c²
c=37 units
