The correct answer is: " √x − <span>2√b " .
</span>_________________________________________________________
The "conjugate" of " √x + 2√b " is: " √x − 2√b " .
_________________________________________________________
Explanation:
_________________________________________________________
In an expression with 2 (TWO) terms; that is, in a "binomial expression",
the "conjugate" of that expression refers to that very expression — with the "sign" in between those two terms—"reverse" (e.g. "minus" becomes "plus" ; or, "plus" becomes "minus" .) .
_________________________________________________________
→ So: We are given: " <span>√x + 2√b " .
</span>
→ Note that this is a "binomial expression" ;
→ that is, there are 2 (TWO) terms: " <span>√x " ; and: " 2√b " .
_________________________________________________________
To find the "conjugate" of the given binomial expression:
</span>→ " <span>√x + 2√b " ;
</span>→ We simply change the "+" {plus sign} to a "<span>−" {minus sign} ; and rewrite:
___________________________________________________________
</span>→ " √x − 2√b " ;
→ which is the "conjugate" ; and is the correct answer:
___________________________________________________________
→ " √x − 2√b " ; is the "conjugate" of the expression: " <span>√x + 2√b " .
___________________________________________________________
</span>→ {that is: " √x − 2√b " ; is the conjugate.}.

The total profit received for all mobile phone manufacturers for all carriers was 1.54 billion
Step-by-step explanation:
Given,
Profit received = 32%
Total profit received = $4.8 billion
Amount of profit received for mobiles = 32% of total profit
Amount received = 
Amount received = 
Amount received = 1.536 billion
Rounding off
Amount received = 1.54 billion
The total profit received for all mobile phone manufacturers for all carriers was 1.54 billion

Jaime is correct,
because when you turn a decimal into percent, you move the decimal two places, you are basically multiplying by 100.<span />
