Answer:

(D) AAA

Step-by-step explanation:

Law of cosines: Law of cosines are mostly used in those cases which includes two sides and one included angle.

Thus, SAS and SSS triangle cases can be solved by the Law of cosines.

Law of sines: Law of sines can be used in those cases which includes one side and an angle opposite to  that angle.

Thus, SAA triangle case can be solve by the law of sines.

Only AAA is the only triangle case which can neither be solved by Law of cosines nor by Law of sines.

Thus, Option D is correct.

Aaron wants to mulch his garden. His garden is x^2+18x+81 ft^2 One bag of mulch covers x^2-81 ft^2 . Divide the expressions and
blsea [12.9K]

Answer:

Step-by-step explanation:

Given

Garden: x^2+18x+81

One Bag: x^2 - 81

Requires

Determine the number of bags to cover the whole garden

This is calculated as thus;

Bags = \frac{x^2+18x+81}{x^2 - 81}

Expand the numerator

Bags = \frac{x^2+9x+9x+81}{x^2 - 81}

Bags = \frac{x(x+9)+9(x+9)}{x^2 - 81}

Bags = \frac{(x+9)(x+9)}{x^2 - 81}

Express 81 as 9²

Bags = \frac{(x+9)(x+9)}{x^2 - 9\²}

Evaluate as difference of two squares

Bags = \frac{(x+9)(x+9)}{(x - 9)(x+9)}

Bags = \frac{(x+9)}{(x - 9)}

Hence, the number of bags is Bags = \frac{(x+9)}{(x - 9)}

Simplify (1/2x^2y)^5
marysya [2.9K]

Start with

\left(\dfrac{1}{2}x^2y\right)^5

We have to raise all terms to the fifth power:

\left(\dfrac{1}{2}x^2y\right)^5 = \left(\dfrac{1}{2}\right)^5\cdot (x^2)^5\cdot y^5

Recall the law

(a^b)^c=a^{bc}

to conclude that

\left(\dfrac{1}{2}x^2y\right)^5 = \dfrac{1}{2^5}x^{10}y^5=\dfrac{1}{32}x^{10}y^5
