Answer:
3.5 hours traveling
2.5 hours stationary
Step-by-step explanation:
When the line is horizontal, the distance isn't changing, so she is stationary, so just add the total time the line is horizontal.
Likewise, all other lines represent traveling.
You divide -15 on both sides to keep the x alone
-240/ -15=16
A negative divided by a negative is a positive so x=16
The two legs are 90° apart, so constitute the "base" and "height".
.. A = (1/2)*b*h = (1/2)*(13 m)*(18.2 m) = 118.3 m^2
Answer:
angle four is vertical to angle 2
The expression that represents the width and length of the square is (x+10).
We factor this expression to find the dimensions. We want factors of 100 that sum to 20; 10(10) = 100 and 10+10=20. This gives us
(x+10)(x+10).
