Hi There! :)
<span>Which numbers should be multiplied to obtain 175^2 − 124^2?

Wayne traveled 90 miles total.
60 miles was 2/3 of the distance.
30 miles is 1/3.
90 miles divided by 4 hours.
90/4
22.5 or 22 1/2 mph
The interior angles of a triangle must add to 180 degrees.
110+5x+2x=180
110+7x=180
7x=70
x=10
Then plug in the x value into each angle expression
5(10)=50 degrees
2(10)=20 degrees
12 feet squared or 3 feet squared. hopefully this helps i got 2 different answers
If you're just integrating a vector-valued function, you just integrate each component:
The first integral is trivial since 
.
The second can be done by substituting 
:
The third can be found by integrating by parts:
