Simplify the expression 2√ 20 − 3√ 7 − 2√ 5 + 4√ 63 .

earnstyle [38]

Answer:

The simplified form is,

$\boxed{\boxed{6\sqrt{5}+9\sqrt{7}}}$

Step-by-step explanation:

The given expression is,

$=2\sqrt{20}-3\sqrt{7}+2\sqrt{5}+4\sqrt{63}$

$=2\sqrt{4\times 5}-3\sqrt{7}+2\sqrt{5}+4\sqrt{9\times 7}$

$=2(\sqrt{4}\times \sqrt{5})-3\sqrt{7}+2\sqrt{5}+4(\sqrt{9}\times \sqrt{7})$

$=2(2\times \sqrt{5})-3\sqrt{7}+2\sqrt{5}+4(3\times \sqrt{7})$

$=4\sqrt{5}-3\sqrt{7}+2\sqrt{5}+12\sqrt{7}$

$=4\sqrt{5}+2\sqrt{5}+12\sqrt{7}-3\sqrt{7}$

$=6\sqrt{5}+9\sqrt{7}$

do you think that a negative sign affects whether or not a number is rational number? Use -8/5 an example.

lina2011 [118]

-8/5 is a rational number because in order to be a rational number it must be able to be written as a fraction. -8/5 is a fraction; therefore, the negative does not affect it.

Need the answer to 2. 3. 7. 8. please help! Really confused on how to do this.

Oduvanchick [21]

2. $\overline{SV}||\overline{TU}$ (this is given in the first sentence)

3. $\angle XSV\cong\angle XUT$ and $\angle XVS\cong\angle XTU$ due to ...

7. ... the alternate interior angles theorem (which holds because $\overline{ST}$ and $\overline{TU}$ are parallel)

8. Because the above establishes that $\Delta SXT\cong\Delta UXV$ , which means $\overline{ST}||\overline{UV}$ , which in turn means $VUTS$ is a parallelogram.
