If a child was born exactly k years ago, how old was the child m years ago?
Answer
a. m + k
b. k - m:::: yes
c. -m
d. m - k
e. m
-------------------------
If 2a + 4b = √k, then (a + 2b)√k = ?
-----
a+2b = sqrt(k)/2
---
Then (a+2b)*sqrt(k) = [sqrt(k)/2][sqrt(k) = k/2
Answer
a. 3k
b. k/2::::yes
c. 2k
d. k
e. k/4
