(15/14)² = 225/196
Step-by-step explanation:
Evaluating the expressions inside parentheses, we can see they are the same, eliminating a bit of work.
Irrational numbers are numbers that do not repeat or terminate. π is a common example. 3+0.4=3.4, this number terminates. 0.444...+0.4=0.8444..., this number repeats.
Answer:
(3, 12)
Step-by-step explanation:
x + y = 15
x - y = -9
add them together
2x + 0y = 6
2x = 6
x = 6/2
x = 3
substitute 3 into any equation, i chose x + y = 15
3 + y = 15
y = 12
check for 2nd equation:
3 - 12 = -9
-9 = -9
