Last week, chen bought 812 gallons of gas at $2.30 per gallon. this week, he bought 4310 gallons of gas at $2.70 per gallon. what was his total cost?

13054.6      

Step-by-step explanation:

multiply 812 by 2.30 then multiply 4310 by 2.70 then add both answers together.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
