Since the 3 lengths of the triangle are given, one can use the Cosine law:
b^2 = a^2 + c^2 -2ac cos(B)
18^2 = 22.5^2 + 13.6^2 -2(22.5)(13.6) cos(B)
B = 53.12 deg
Using Sine law for C
18/(sin (53.12)) = 13.6/(sin ( C))
C = 37.19 deg
<span>(6x 2 + 11x - 35) ÷ (3x - 5) Please do not include parentheses in your answer. the answer is 2x+7</span>
Parallel lines<span> are coplanar </span>lines<span> that do not intersect</span>
Knowing that your area is:

you can find the radius as:

;
With this you can evaluate the circumference as:
Here is your answer! The coefficient of xy is 6. To solve this problem, you need to multiply your two polynomials together. I used the FOIL Method- multiply the First two, the Outside two, the Inside two, and the Last two. You can see how I did it on the picture attached. Next, the answer that you get as a result from FOILing is your polynomial. If you look at the number before xy, that is the coefficient. A coefficient is a number that is right before and attached to a variable. I hope this helps you! :))
