Answer:
Step-by-step explanation:
we know that
In this problem
The value of x represent the radius of the circle
so
Applying the Pythagoras theorem in the right triangle of the figure, you can find the radius of the circle O
see the attached figure to better understand the problem
square root both sides

Answer:
The number that would be added to make 
a complete square is 
Step-by-step explanation:
We need to solve the expression using completing the square method.
Completing square method is of form: 
We need to find the term, that it a complete square
The middle term is -19x so, it can be made as: -2(x)(19/2) according to the formula a^2-2ab+b^2
We have a=x and b=19/2
So, adding and subtracting (19/2)^2
So, the number that would be added to make a complete square is
Answer:
The slope of the given line and a line parallel to it is
5
2
.
Explanation:
Given:
5
x
−
2
y
=
11
is the standard form of a linear equation.
A line parallel to this line has the same slope. To determine the slope, solve for
y
to change the equation to slope-intercept form:
y
=
m
x
+
b
,
where:
m
is the slope and
b
is the y-intercept.

x
−
2
y
=
11
Subtract
5
x
from both sides.
−

y
=

x
+
11
Divide both sides by

Answer:
−8a2−3b+76
Step-by-step explanation:
=13a2+−3b+−21a2+76
Combine Like Terms:
=13a2+−3b+−21a2+76
=(13a2+−21a2)+(−3b)+(76)
=−8a2+−3b+76
