Answer:
242cm^2
Step-by-step explanation:
The formula for surface area of a rectangular(assuming that's what you have) is Perimeter of the Base(height) + 2(Area of the Base)
Or you could add up all the sides, or use this formula
SA=2(length*width)+2(length*height)+2(height*width)
2×(10×7 + 10×3 + 7×3)

Answer:

Step-by-step explanation:
We look for where
. The way you find the answer is first, find the point
. Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).
Using this method here, we see that
intersects our line at
, so
.
