Answer:
x=-2
Step-by-step explanation:
2(x+3)-10=4x
2x+6-10=4x
6-10=2x
-4=2x
-2=x
Max needs to run 15 laps around the track.
Step-by-step explanation:
Given,
Distance Max wants to run = 512 miles
Length around the track = 34 mile
34 miles = 1 lap
1 mile = 
512 miles = 
512 miles = 15.06 laps
Rounding off to nearest whole number;
512 miles = 15 laps
Max needs to run 15 laps around the track.

Answer:
3cm/s
Step-by-step explanation:
Area of a square is expressed as:
A = L²
Rate of change of area is expressed as:
dA/dt = dA/dL•dL/dt
Given that
dA/dt = 24cm²/s
L = 4cm
Required
dL/dt
Since dA/dl = 2L
dA/dl = 2(4)
dA/dl = 8cm
Subatitute the given values into the formula
24 = 8 dL/dt
dL/dt = 24/8
dL/dt = 3cm/s
