Have you tried sketching this situation?
x is the length of the side of his original office. If he adds 15 ft, then the area, A, would be x times (x+15). 15x represents the floor area of the addition.
Answer:
133.06 miles per hour
Step-by-step explanation:
Distance =2438.9 miles
Time=18 hours 20 minutes.
First we convert the time to hour
60 minutes = 1 hour
20 minutes=(20/60) hour=0.33
Therefore her time=18+0.33 hour=18.33hour
We are to determine the average speed of her flight in miles per hour.
rate=distance/time
=2438.9/18.33
=133.06 miles per hour
Her average speed is 133.06 miles per hour
Answer:
Step-by-step explanation:
y - 3 = 2(x + 2)
y - 3 = 2x + 4
y = 2x + 7
I wasn’t sure if I should include all the numbers if they were doubles but you get the idea. Hope this helps!
6√2 or 8.48528137424
use the pythagorean theorem
9^2=3^2+x^2
81=9+x^2
72=x^2
√72 = 6√2 or 8.48528
