Consider that x = 5 and y = 7. Which statement is true about x + y? A)The sum of x and y is a rational number. B)The sum of x and y is an imaginary number. C)The sum of x and y is an irrational number. D)The sum of x and y is neither rational nor irrational.

The answer is 12

Step-by-step explanation:

because 7 plus 5 is 12

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
