Answer:
80
Step-by-step explanation:
Subtract 60 on both sides to get -40.
You are left with 40x=-40
Divide both sides by 40 to leave x by itself.
You get x=-1.
Answer:
x<−3+√1012 or x>−3−√1012

Answer: I think it’s B
Not sure tho
Explanation
Answer:
A = 169π/4
Step-by-step explanation:
From these two given points we find the length of the diameter of this circle, using the Pythagorean Theorem:
d^2 = (8 - 3)^2 + (13 - 1)^2, or
d^2 = 25 + 144 = 169
Thus, the diameter, d, of this circle is √169, or 13.
The radius is thus 13/2 units.
The area formula is A = πr^2. Here the area is
A = π(169/4), or A = 169π/4
