Answer:
hey mate I guess ur question is incomplete......after greatest what is it? plz check
a)
the average speed, well it does 10 ft in 1.6 secs, so is simply their quotient, 10/1.6 = 6.25 ft/s on average.
b)
over the horizontal, well, it covered horizontally 9.25 ft in those 1.6 secs, so their quotient is 9.25/1.6 = 5.78125 ft/s on average.
c)
we don't know the vertical distance, but

so, it covered vertically about 3.8 ft in those 1.6 secs, so then 3.8/1.6 = 2.375 ft/s on average
+Well you need to multiply 11.3 times 4.5 per each triangle
Also you need to find the base which is a square
So 5.1 times 5.1 which is technically 5.1 squared. You add from there
EQUATION: 4(11.3 x 4.5) + 5.1 squared
You should get 229.41
Answer:
20x + 276
Step-by-step explanation:
P = 2 (2(4x-3) + 2x+12^2)
= 2 (8x - 6 + 2x + 144)
=2 (10x + 138)
=20x + 276
