2.1.2, 2-14: The jackrabbit is jumping along and encounters a brick wall that is 2.5 feet high and 1 foot wide. Can he clear the wall if his jump is the same height and width as in problem 2‑13? If so, how close to or far away from the wall should the jackrabbit be when he jumps? Use your model to decide.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

1; 35 is the ratio

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
