3x+15 , this expression correctly combines the like terms
Answer:

Step-by-step explanation:
If a horizontal line intersects the graph of a function in all places at exactly one point (the horizontal line test), the inverse of the function is also a function.
For example, the inverse of a hyperbola (like ƒ(x) =1/x) is a function, because every horizontal line intersects with the graph at exactly one point.
However, the inverse of a parabola (like ƒ(x) = x²) is not a function, because a horizontal line intersects with the graph at two points.
Since tenths are 10 hundredths in each, 4 tenths equal to 40 hundredths.
Are we supposed to find the area? If so, It's 36 because 6 times 6 equals 36 :p Hope I helped.
