Answer:
5v^3
Explanation:
Move v^-3 to the numerator using the negative exponent rule 1/b^-n = b^n.
Hi there!
First work out the parenthesis. Remember that a negative times a positive ends up with a negative. A negative times a negative ends up with a positive.
Subtract 6x from both sides.
Add 32 to both sides.
Divide both sides by 6.
Now we've found our solution.
~ Hope this helps you!
It is true. Have a great day!

Answer: 29 miles (approximate)</h3>
======================================================
Explanation:
Segment AB is already given to be 19 miles long.
I'm assuming your teacher meant to ask about side BC, which is side 'a' since it's opposite angle A.
Use the law of cosines to find the missing side
a^2 = b^2 + c^2 - 2*b*c*cos(A)
a^2 = 12^2 + 19^2 - 2*12*19*cos(138)
a^2 = 843.874040417691
a = sqrt(843.874040417691)
a = 29.0495101579647
a = 29 when rounding to the nearest whole number
Side BC is roughly 29 miles long.
