Answer:
Prime numbers
Step-by-step explanation:
Consider that a prime number is a number with only two factors: 1 and itself (Example: {2, 3, 5, 7, ...}). Also, state that 2 is the only even prime number.
The set of all even numbers within the set of prime numbers can be described as {2}. Therefore, the universal set is all prime numbers itself.
1470 because 0.52 is close to the whole
<h2>(x + 4) (x + 4)</h2>
Step-by-step explanation:
= x² + 8x + 16
= x² + 4x + 4x + 16
= x (x + 4) + 4 (x + 4)
= (x + 4) (x + 4)

To check the answer, sub in 67 for x and 25 for y in both equations...because for it to be a solution, it has to satisfy both of the equations.
(67,25)...x = 67 and y = 25
x + y = 92
67 + 25 = 92
92 = 92 (correct)
y = 3x - 4
25 = 3(67) - 4
25 = 201 - 4
25 = 197 (incorrect)
so (67,25) is NOT a solution to this system of equations because it does not satisfy both of the equations
