Answer:
6
Step-by-step explanation:
Multiply 7x+3 by 2. When you get 14x+6, set equal to 90 and solve for x.
Undefined (not a real number)
The square root of -256 would result in an imaginary number so by terms, it's "not real". The imaginary number would be 16i. 16x 16 =256, but since it's negative, it's √16 √16i.
Answer:
-8xy+3x+2z
x+3yz-8
Step-by-step explanation:
So since the distance (d) is determined by the speed (60 mph) multiplied by the time travelled (t), you would write the equation as
d = 60t
This shows the relationship between the distance and the time you travel at 60 mph. Therefore if you travel for example 2 hours, you will have gone 120 total miles.
I hope this helped :)
