Mutiply the bracket by -2

(-2)(2y)=-4y

(-2)(-3)= 6

4y^3-4y+6+y

4y^3-4y+y+6 ( combine like terms)

The gardening club at school is growing vegetables. The club has 300 square feet of planting beds. Cucumber plants require 6 squ
nadya68 [22]

<em>The question doesn't ask anything in particular, I will show the set of inequalities defined in the problem.</em>

Answer:

<em>System of inequalities:</em>

6c+4t\leq 300

c>0\\t > 0\\c+t\geq 60

Step-by-step explanation:

<u>Inequalities </u>

The express relations between expressions with a sign other than the equal sign. Common relationals are 'less than', 'greater than', 'not equal to', and many others.

The gardening club at school has 300 square feet of planting beds to plant cucumber and tomato. Each cucumber plant requires 6 square feet of growing space and each tomato plant requires 4 square feet of growing space. We know the total area cannot exceed 300 square feet, so

6c+4t\leq 300

Being c and t the number of cucumber and tomato plants respectively.

We also know the students want to plant some of each type of plant and have at least 60 plants. This lead us to more conditions

c>0\\t > 0\\c+t\geq 60

<em>Note: The set of inequalities shown is not enough to uniquely solve the problem. We need something to maximize or minimize to optimize c and t</em>

What is the conjugate? √x + 2√b
Llana [10]
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.}.
