Answer 4

Answer 7

got a triangle and one half base times hight is one half of one is one half

Answer 8

because y = x is just a line and if you draw it from x = 0 to x = 1 you see a right triangle with base one and hight one.

Answer 9

of course you could also take the anti-derivative and plug in the numbers but that is too much work for this problem

Answer 10

i think i meant "height"

Answer 11

yes

Answer 12

then you got it!

Answer 13
