Answer:
option c, x = 3
Step-by-step explanation:
Given:
- f(x) =
Since both equal f(x) they must be equivalent as well,
Apply exponent rule, 3 x 3 x 3 = 27
hence x = 3
Answer:
2 + h = 14 and k - 25 = 2
Step-by-step explanation:
An equation has an equal sign.
Apparently, your answer choices are of the form ...
(math expression) and (math expression)
In order for this to be "only equations", each "math expression" must contain an equal sign. That is, you must have ...
( ... = ... ) and ( ... = ... )
Something like ...
c -14 and d +134
contains no equal signs, so has no equations.
It looks like your appropriate choice is ...
2 + h = 14 and k - 25 = 2
2(a+3)+3(2a-1)
=2a+6+6a-3
=8a+3
