Answer:
x=19
Step-by-step explanation:
First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:
Then you square the numbers that you currently have:
Then subtract 225 from both sides to isolate the x:
This gives you the equation:
Then take the square root of both sides which gives you:
Then round to the nearest whole number which gives you x=19
Answer:
The first one
Step-by-step explanation:
This is a constant function, i.e. the value for y doesn't depend on x. So, every x value will lead to the same y value, in this case 4.
This implies that the graph is a horizontal line, composed by all points like (x,4), where x can be any value and 4 is fixes as the y coordinate.

Answer:
C24
Step-by-step explanation:
You start by taking 41 and 22.
Take 9 from both numbers to represent the students taking both courses.
41-9=32
22-9=13
Then 78-32(French Students)-13(German Students)-9(Two Course Students)
78-32-13-9=
78-54=
24
