Answer:
Step-by-step explanation:
1. Value of x
The diagonals of a rectangle are equal, so
PR = QS
2. Length of each diagonal
PR = 11x - 20 = 11×18 - 20 = 198 - 20 = 178
QS = x + 160 = 18 + 160 = 178
The length of each diagonal is 178.
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! :))
