2x - the first and the smallest even integer
2x+2 - the second even integer
2x+4 - the third even integer

These three consecutive even integers are -54, -52 and -50.
Answer:
The 3 numbers must be multiples of 3, 4, and 5
Step-by-step explanation:
Pythagorean Triples are numbers that you know will come out perfectly in the Pythagorean Theorem. But the easiest way to explain this is to show you an example.
Say you're given the numbers 12, 16, and 20.
They should be able to be divided by the same number and equal 3, 4, and 5.
In this case, the number is 4.
12/4=3
16/4=4
20/4=5
So, this is a 3-4-5 triangle, or a Pythagorean Triple.
20 it the least common multiple of the numbers given
19.698 feet of cable would be needed, this would round up to 20 feet total.
Answer:
Two
Explanation:
The solution of a system of equations is defined as the values which satisfies both equations.
Graphically, the solutions are represented by the points of intersection between the two equtaions.
In the given graph, we have a circle and a line, we can note that these two intersect in two points.
This means that the system has two solutions
Hope this helps :)
