\textsf{\qquad\qquad\huge\underline{{\sf Answer}}}

Let's solve ~

\qquad \sf  \dashrightarrow \:(2 {}^{ \frac{2}{x} } ) \sdot(2 {}^{ \frac{4}{x} } ) = 2 {}^{12}

\qquad \sf  \dashrightarrow \:(2 {}^{ \frac{2}{x} +  \frac{4}{x}  } ) = 2 {}^{12}

\qquad \sf  \dashrightarrow \:(2 {}^{   \frac{6}{x}  } ) = 2 {}^{12}

Now, since the base on both sides are equal, therefore their exponents are equal as well ~

\qquad \sf  \dashrightarrow \: \dfrac{6}{x}  = 12

\qquad \sf  \dashrightarrow \:x =  \dfrac{6}{12}

\qquad \sf  \dashrightarrow \:x =  \dfrac{1}{2}

or

\qquad \sf  \dashrightarrow \:x = 0.5

Hope you got the required Answer ~

What is the factored form of the expression?
Georgia [21]

Answer: The answer is (d) (4x+7)(7x+8).


Step-by-step explanation: Given equation to be factored is

28x^2+81x+56.

The given expression is quadratic, so we can factor it into two linear factors, by using the following factorisation rule.

x^2+(a+b)x+ab=(x+a)(x+b).

So, the given equation can be factorised using the above rule. The factorisation is as follows.

28x^2+81x+56\\\\=28x^2+49x+32x+56\\\\=7x(4x+7)+8(4x+7)\\\\=(4x+7)(7x+8).

Thus, the correct option is (d).

find the perimeter and total area of the composite shape shown below. All measurements are given in inches. Use pie=3.14 in any
kozerog [31]

Square part of perimeter = 40.

Half circle = 25.135.

Together 65.135 is perimeter.

Area of square: 192

Are of half circle: 100.53.

Together 292.53

Rounded =292.48 I guess, its the most logical option since I don't see it and the only one that fits perimeter answer.

So its the 3rd question I believe, you may want to double check.

Hit the heart if it was helpful.
