Answer:
x>8/5
Step-by-step explanation:
take the square root of both sides
8/5 < x< 12/5
(2 - x)^2 < 4/25
Take the square root of each side
sqrt((2 - x)^2) <±sqrt( 4/25)
Make two equations
2-x < 2/5 2-x > -2/5
Subtract 2 from each side
2-x-2 < 2/5 -2 2-x-2 > -2/5-2
-x < 2/5 - 10/5 -x > -2/5 - 10/5
-x < -8/5 -x > -12/5
Multiply by -1, remembering to flip the inequality
x> 8/5 x < 12/5
32/a = a/2
a^2 = 64
a = 8
b^2 = 8^2 + 2^2
b^2 = 64 + 4
b^2 = 68
b = 2√17
answer is the first option
a = 8, b = 2√17
246.2
Hope this helps!
Um i think it is B and i'm gonna be honest i'm not as good with math as i am in reading.
