Aand b are centres of two circles of radii 8 cm and 1 cm such that ab =13 cm and angle acb =90 degree where c is the centre of another circle which touches the above two circles . find the area of the circle with centre c

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
