Rationalize the denominator of the given expression

Grace [21]

You multiply top and bottom of the fraction by the conjugate of 5 - √2 which is 5 + √2. This produces a rational denominator:-

= √7 ( 5 + √2) / (5 - √2)(5 + √2)

= √7 ( 5 + √2) / (25 -2)

= (√7 ( 5 + √2)) / 23 answer

3. Carlos cuts blue parallelograms and larger red parallelograms to use in his decoupage. He realizes the parallelograms are sim

Answer:

The area of the larger parallelogram is $180\ cm^{2}$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is the scale factor

Let

z------> the scale factor

$z=\frac{24}{16}=1.5$

step 2

Find the area of the larger parallelogram

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z------> the scale factor

x------> the area of the larger parallelogram

y-------> the area of the smaller parallelogram

$z^{2}=\frac{x}{y}$

we have

$z=1.5$

$y=80\ cm^{2}$

substitute the values

$1.5^{2}=\frac{x}{80}$

$x=80*(1.5^{2})=180\ cm^{2}$
