Answer:
67 cents
Step-by-step explanation:
2 quarters: one quarter is 25 cents, so two will be 50 cents.
5 cents: Just 5 cents.
1 dime: A dime is 10 cents.
2 cents: 2 cents!
Add everything up: 50 + 5 + 10 +2 = 67 cents!

In a regular decagon like the one shown in the picture each angle is 144 degrees and it all adds up to 1,440. If you want proof search up "angle of a decagon"
-28x+196 is equal to (x-14)^2 (factored version)
