Which product should tomas choose?
tomas learned that the product of the polynomials (a + b)
(a? - ab + b) was a special pattern that would result in a
sum of cubes, a3 + b3. his teacher put four products on the
board and asked the class to identify which product would
result in a sum of cubes if a = 2x and b = y.
(2x+y)(2x + 2xy -
(2x + y)(4x2 + 2xy - y2)
(2x + y)(4x2 - 2xy + y2)
(2x + y)(2x2 - 2xy + y2)

step-by-step explanation:

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
