Answer:
P(A and B) = 7/80
Step-by-step explanation:
The given values of the probabilities of the different events are;
P(A) = 7/20
P(B) = 7/20
P(A or B) = 49/80
P(A and B) = Required
We have by probability theory for any event;
P(A or B) = P(A) + P(B) - P(A and B)
Therefore;
P(A and B) = P(A) + P(B) - P(A or B)
Plugging in the values gives;
P(A and B) = 7/20 + 7/20 - 49/80 = 7/80
∴ P(A and B) = 7/80
Step-by-step explanation:
2(3x-5)=5x-3
6x -10 =5x -3
x=7
The sum of the squared legs must give the squared hypotenuse:
But of course we can only accept the positive solution, because 
is a length and can't be negative.
