Answer:
No
Step-by-step explanation:
you can check with the pythagorean theory
64 + 81 = 144
145 = 144
this is not true, therefore those side lengths do not make a right triangle.
A = a + b over 2
First multiply both sides by 2:
2A = a+b
Now subtract a from both sides:
b = 2A - a

Answer:
y

(
x
−
12
)
Explanation:
The point-slope form of the equation of the line is usually written in formula form as
y
−
y
1
=
m
(
x
−
x
1
)
To find a specific line, replace the m with the value for the slope, here m = -3, and the coordinates of the point using the given coordinates,
(
x
1
,
y
1
)
=
(
12
,
5
)
.
Usually the brackets are removed and the equation rearranged.
