Step-by-step explanation:

Answer:
9.784
Step-by-step explanation:
remember this formula for right triangles (a^2+b^2=c^2)
so 7.4^2+6.4^2=c^2
54.76+40.96=c^2
95.72=c^2
this is where we do this

square root of 95.72 is around 9.784
Answer:
90 MPH
Step-by-step explanation:
2700 / 30 = 90
Answer:
Since the slope of the line x= - 5 is infinite
The line will be parallel to y axis.
And the line passes through - 2, so the equation will become x= -2
