Should be A because you do 60=1.6x+48 and solve and that should give u 7.5 or 7 1/2
8x + 42 = 90
8x = 90 - 42 = 48
x = 48/8 = 6 answer
Answer:
4 - i
Step-by-step explanation:
Intuitively, the answer will be 4 - i, as the other numbers are too big to have a square as small as 17i. Also, we know that i will not be in the end result, which means that we should have a negative in the result as well.
To test this, we can simply treat 4 and -i as the sides of a right triangle and find the hypotenuse:

So indeed the answer is 4 - i
