Answer:
D. x = 10
Step-by-step explanation:
Perimeter = the sum of all sides lengths
Perimeter = 30 (in this case)
so...

Step 1. Dividing 3 to both sides

Step 2. Add 5 to both sides

Step 3. Solve for x
Since x + x = 20, to solve for one of the x means solving for the other x
so since 2 x's are being added with the same value, divide 20 by 2.
x = 10
Answer:
8.2 million years
Step-by-step explanation:
The time can be found from ...
time = distance/speed
time = (47.0×10^4 m)/(5.7×10^-2 m/yr) = 8.2×10^6 yr
It will take about 8.2 million years for LA to have the same latitude as SF.
