The dulcimer has the following dimensions
and height h

Operating
Is the required polynomial
Answer:
4. x = 11
5. x = -13
Step-by-step explanation:
4. 3x + 7 = 5x - 15
-7 -7
3x = 5x - 22
-5x -5x
-2x = -22
-2x/-2 = -22/-2
x = 11
5. 3(2x - 5) = 9x + 24
6x - 15 = 9x + 24
+15 +15
6x = 9x + 39
-9x -9x
-3x = 39
-3x/-3 = 39/-3
x = -13
Hope this helps, have a great day:)
