The only irrational number there is C
Answer: 201.06
Step-by-step explanation:
To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before.

{ x + 3 y = 7 * ( - 2)
2 x + 4 y = 8
{ - 2 x - 6 y = - 14
2 x + 4 y = 8
_______________
-2 y = - 6 * ( -1)
2 y = 6
y = 6 / 2
y = 3
For x :
2 x + 4 y = 8
2 x + 4 * ( 3) = 8
2 x + 12 = 8
2 x = 8 - 12
2 x = - 4
x = - 4 / 2
x = - 2
Solution: x = -2 and y = 3

Answer:
<u>Part 1:</u> Find (f/g)(4) = 3
<u>Part 2:</u> Find (f+g)(4) = 28
Step-by-step explanation:
<u>Part 1:</u> Find (f/g)(4):
(f/g)(4) means <em>divide f function by g function and simplify it. Then plug in 4 into x of that simplified function.</em>
Let's do this:

Plugging in 4 into x gives us:

The answer is 3
<u></u>
<u>Part 2:</u> Find (f+g)(4):
(f+g)(4) <em>means add f function and g function and simplify it. Then plug in 4 into x of that simplified function.</em>
Let's do this:

Plugging in 4 into x gives us:

The answer is 28
