Four less than 6 times a number gives 38.

x = a number

6x - 4 = 38. Add 4 to both sides.

6x = 42. Divide 6 from both sides.

x = 7.

7

Step-by-step explanation:

The answer is 7 because 6 times 7 is 42.

42-4 is equal to 38.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

the answer

b. they are parallel and will never intersect.
