Answer:

C 4:1

D 24:6

F 1200:300

Step-by-step explanation:

The given ratio is  \frac{12}{3}

Simplify

Divide by 3 both numerator and denominator

\frac{4}{1}

<u><em>Verify each case</em></u>

case A) we have

\frac{6}{1}

Compare with the given ratio

\frac{6}{1} \neq \frac{4}{1}

therefore

The ratio is not equivalent

case B) we have

\frac{1}{4}

Compare with the given ratio

\frac{1}{4} \neq \frac{4}{1}

therefore

The ratio is not equivalent

case C) we have

\frac{4}{1}

Compare with the given ratio

\frac{4}{1}=\frac{4}{1}

therefore

The ratio is equivalent

case D) we have

\frac{24}{6}

Simplify

Divide by 6 both numerator and denominator

\frac{4}{1}

Compare with the given ratio

\frac{4}{1}=\frac{4}{1}

therefore

The ratio is equivalent

case E) we have

\frac{15}{6}

Simplify

Divide by 3 both numerator and denominator

\frac{5}{2}

Compare with the given ratio

\frac{5}{2} \neq \frac{4}{1}

therefore

The ratio is not equivalent

case F) we have

\frac{1,200}{300}

Simplify

Divide by 300 both numerator and denominator

\frac{4}{1}

Compare with the given ratio

\frac{4}{1}=\frac{4}{1}

therefore

The ratio is equivalent

case G) we have

\frac{112}{13} ----> irreducible

Compare with the given ratio

\frac{112}{13} \neq \frac{4}{1}

therefore

The ratio is not equivalent

If x^(2) - 2 = 2^(2/3) + 2(-2/3) prove that x = 2^(1/3)+2^(-1/3)
dusya [7]

Step-by-step explanation:

x² - 2 = 2^(2/3) + 2^(-2/3)

x² = 2^(2/3) + 2 + 2^(-2/3)

x² = (2^(1/3))² + 2 × 2^(1/3) × 2^(-1/3) +

(2^(-1/3))² (It is in the form of a²+2ab+b²)

x² = (2^(1/3) + 2^(-1/3))²

x = 2^(1/3) + 2^(-1/3)
