Answer:
43
Step-by-step explanation:
If x = 4, then plug in an x in the given equation
7(4) + 15 = 43
Therefore h(4) = 43
I hope this helps! :)
We know, Area = Length * Width
So, with area 42, dimensions could be: 1 * 42
2 * 21
3 * 14
6 * 7
Just draw the lines with that measures, two pair of two equal opposite lines.
Hope this helps!
