Answer:
√2 x √2 = 2
Step-by-step explanation:
Square roots that aren't perfect squares are irrational.
For Ex: √2 is irrational.
But √2 x √2 = √4 = 2. 2 is rational
Ex. 2 : √8 x √2 = √16 = 4. 4 is rational

Answer:
Greater ; Greater
Smaller ; Greater
Step-by-step explanation:
Slopes
First row
A: 15/2
B: (25-12.5)/(4-2) = 12.5/2
A has a greater slope than B
-4x + 2y = 8
2y = 4x + 8
y = 2x + 4
A: 2
B: 3/2
A has a greater slope than B
Second Row
A: (2.6-2)/(3-0) = 0.6/3 = 0.1
B: (5-4)/(4-0) = 1/4 = 0.25
A has a smaller slope than B
A: 60
B: (325-50)/5-0) = 275/5 = 55
A has a greater slope than B
