W=4
I hope this helps! Any questions?
Answer:
See below
Step-by-step explanation:
(a) There is a number whose cube is equal to 2.
(b) The square of every number is at least 0.
(c) There is a number that is equal to its square.
(d) Every number is less than or equal to its square.

(By the way, this last statement <u>is not true</u> when 0 < x < 1)
False, No Triangle can be formed with those side lengths. Here's why:
The sum of side a and side a has to be greater than side c.
a+b>c
3+5= 8
8 is not greater than 9
Buns cost .75 so 7 buns. If you need an equation 2x + 1.25= 15.25
I think this is the Transitive postulate of equality.
Personally I can't see much point in giving labels to these equalities.
