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,

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

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

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

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

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

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

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

A tree that is 3 feet tall is growing at a rate of 32% each year. How tall will it be in 3 years?

pashok25 [27]

Answer: 5.88 feet tall

Step-by-step explanation:

Using this formula

Interest =principal×rate×time/100

Principal is the actual growth=3ft

Rate is the 32%

Time is 3yrs

Interest =3×32×3/100

Interest =2.88

To get the value for 3yrs,add the interest to the principal value

Exact value in 3yrs=

3+2.88

=5.88 feet tall
