The value of x in the diagram is 8 feet that makes the combined area of the house and the porch to be 733 ft²
<h3>How to calculate
area?</h3>
Combined area = big rectangle + smaller rectangle - triangle
Hence:
733 = (13 * (59 - x)) + (x * 9) - 0.5(9 - 7) * (x - 6)
733 = 767 - 13x + 9x - x + 6
x = 8 feet
The value of x in the diagram is 8 feet that makes the combined area of the house and the porch to be 733 ft²

Answer:
(C) 10m + 7n - 14
Step-by-step explanation:
[Q-R]+[S-T] =[(7m+3n)-(11-2m)]+[(n+5)-(-m-3n+8)]=
=[7m+3n-11+2m] + [n+5+m+3n-8]=[9m+3n-11] + [4n+m - 3]=
=9m+3n-11+4n+m-3=10m + 7n - 14
