Part B: I think the relation that has the greater value when x=6 is f(x) = 7x - 15 because:
7(6) - 15 = 27 which is greater than the output of 14.
Part C: the value of x would be 3 because:
f(x) = 7x - 15
6 = 7x - 15
+ 15 +15
21 = 7x
3 = x
Sorry if any of this is wrong.

Width = 24 yards
Length = 24 x 5 = 120 yards
Area =

Hope this helps. - M
Sum of angle in a triangle is 180, so 33+70+x=180
x=77
x and y are vertical angles so y=77
B. cdb ....angle cdb is adjacent to angle adb because they have a common side (line db)
