$78.17 rounds to $78
15% of $78 = $11.70 which rounds to $12
Answer:
a= 760 b=285 c=1045
Step-by-step explanation:
just did the math
can I get brainliest?
4X,X^2,_
Common difference=12
second term - first term=12
X^2-4x=12
subtract 12 from both sides
X^2-4X-12=12-12
X^2-4X-12=0
now its a quadratic equation, so use either factor method or quadratic formula,
X^2-6X-2X-12=0
take common
x(X-6)-2(x-6)=0
x-2)(x-6)=0
so x is either 2 or 6
now use them to find the third term
Answer:
-x+11
