Given expression is 7 \sqrt{50x^{15}y^{21}} where x and y are non negative.

Now we have to simplify this to find the correct matching choice.

7 \sqrt{50x^{15}y^{21}}

=7 \sqrt{25*2x^{15}y^{21}}

=7 \sqrt{25*2x^{14}*xy^{20}*y}

=7*5x^{7}y^{10} \sqrt{2*x*y}

=35x^{7}y^{10} \sqrt{2xy}

Which best matches with choice D.

Hence final answer is 35x^{7}y^{10} \sqrt{2xy} .

15 points for someone who can answer & explain this to me thanks
iris [78.8K]

Answer:

see explanation

Step-by-step explanation:

Given

\frac{9}{a^2+9a+20} , \frac{7a}{a^2+11a+28}

Factor the denominators of both fractions

\frac{9}{(a+4)(a+5)} , \frac{7a}{(a+4)(a+7)}

The lowest common denominator of both fractions is (a + 4)(a + 5)(a + 7)

Multiply numerator/denominator of first fraction by (a + 7)

Multiply numerator/denominator of second fraction by (a + 5 )

\frac{9(a+7)}{(a+4)(a+5)(a+7)} , \frac{7a(a+5)}{(a+4)(a+5)(a+7)} , then

\frac{9a+63}{(a+4)(a+5)(a+7)} , \frac{7a^2+35a}{(a+4)(a+5)(a+7)}

The length of a rectangle is 18 centimeters less than five times it's width. It's area is 35 square centimeters. I need to find
Fiesta28 [93]
\frac{(5x-18)(x)}{2} =35
(5x-18)(x)=70
5x^2-18x-70=0
By the time you factorize this, you will get
x = 5.9521078984053 or <span>-2.3521078984053
