Answer:
24 meters
Step-by-step explanation:
Use the pythagorean theorem
18² + x² = (x + 6)²
Expand
324 + x² = x² + 12x + 36
Subtract x² from both sides
324 = 12x + 36
Subtract 36 from both sides
288 = 12x
Divide both sides by 12
24 = x
9.268
43
If x = 4, then plug in an x in the given equation
7(4) + 15 = 43
Therefore h(4) = 43
I hope this helps! :)
