Please answer this. very important! :))

Total length = 14h + 14b + 42

Total length (h) = 2h . 7

Total length (h) = 14h

Total length (b) = 2(b + (b + 1) + (b + 2) + ... + (b + 6))

Total length (b) = 2(7b + (1 + 2 + ... + 6))

Total length (b) = 2(7b + 21)

Total length (b) = 14b + 42

Total length = total length (h) + total length (b)

Total length = 14h + 14b + 42

Total length = 14h + 14b + 42

25

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
