What is the series you are referring too?
Since the three angles of a triangle add to give 180°
The the size of the largest angle 4 = 180° ×
= 180° ×
∴ the size of the largest angle = 80°
So the questioon is asking for how many gass refils she would have saved so we want to find how many gas refils equals to the cost of the car so
3.49x=20,599
divide both sides by 3.49 and get x=miles=5902 gas refils
each gass refil fo r the truck is every 16 mile so 16 times 5902 or 94432 miles
a^2 evaluates to
a^2+a evaluates to
Multiply the exponent of a by 2giving
The answer is
a^2 evaluates to
+ =
The answer is
a^2+a+a^2 evaluates to
