Answer:
if x was 4 then the answer would be 36.
Step-by-step explanation:
28+8(4−3)
=28+(8)(1)
=28+8
=36
Answer:
relationship between base and perpendicular is given by tan angle
tan ?=perpendicular./base
tan?=5/16
?=tan-¹(5/16)=17.35=17
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.}.

Answer:
Step-by-step explanation:
Subtract v from both sides
Simplify
Switch sides
Group like terms
Subtract the numbers: 2 - 42 = -40
Add 40 to both sides
Simplify
Divide both sides by 7
Simplify
