Answer:
67
Step-by-step explanation:
With the information of f(2) = 22-5, you can assume the equation will be f(x) = 11x-5. Using this, you can calculate f(5) by doing 11(5)-5, which is 50. 22-5 is 17, so 50+17=67
70 ft because 7 is bigger than 5 and 7x10=70
(8,12)(14,3)
Use midpoint formula
(X1+x2/2, y1+y2/2)
Substitute with your points
(8+14/2, 12+3/2)
Solve each
(22/2,15/2)
Cancel common factor 2
(2×(4+7)/2(1),15/2)
Simplify
(4+7/1,15/2)
This is your midpoint
(11, 15/2)
30 divided by 3. Their are 3 sets of ten by 30 positives
