Can someone help! I know the answer I just need step by step!
baherus [9]

Answer:

4 \sqrt{2}

Step-by-step explanation:

Rewrite 32 as the product of 16 and 2:

\implies \sqrt{32}=\sqrt{16 \cdot 2

Apply exponent rule \sqrt{a \cdot b}=\sqrt{a}\sqrt{b}

\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}

Rewrite 16 as 4²:

\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}

Apply exponent rule \sqrt{a^2}=a

\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}

The length of a triangel is three times its with.if the perimiter is at its most 112 centemeters,witch is the greates possible v
iris [78.8K]
I am assuming you do not mean The length of a triangle and you mean The length of a rectangle because the answer you given are the formula for the perimeter of a rectangle. With that said, the answer is D<span>.2w+2*(3w)112

The perimeter of a rectangle can be found by the following equation:

2L + 2W = P
OR 
P = 2L + 2W
The equation </span>P = 2L + 2W is read perimeter = 2 times Length + 2 times width

The Question:
<span>The length of a rectangle is three times its width.if the perimeter is at its most 112 centimeters ,which is the greatest possible value of the the width.
</span>
The length of a rectangle
This means the perimeter 

is
The word is means to use an equal sign

three times its width
This means 3 times w or 3w 
The w = width

perimeter is at its most 112
This means <=
<= means less than or equal to

Ok so lets look at our equation 

2L + 2W = P
2w + 2(3w) <= 112

What is the answer for this math problem 6x&gt;12
k0ka [10]

Answer:

The correct answer is:   " x  >  2 "  .

______________________________________________________

Step-by-step explanation:

______________________________________________________

Given the inequality:

    " 6x   >  12  "  ;

Solve in terms of "x" :

______________________________________________________

Divide each side of the inequality by "6" ;

   to isolate "x" on one side of the inequation; & to solve in terms of "x" ;

                 →  " 6x  / 6  >  12 / 6  "  ;

   to get:

                 →  "  x  >  2 " .

______________________________________________________

Hope this is helpful to you.

     Best wishes to you in your academic pursuits
