4.68 tons since you would multiply 2.1+0.5=2.6×1.8=4.68 tons
Answer:
I think first add the side 137+ 127 +118=382 / 382cm
Answer:
the answer is probably inverse or joint or combined,really haven't seen this type of variation before
You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
Just find the average and whatever is more than like say 5 away is an out lier
