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.

Karo-lina-s [1.5K]

Answer:

B

Step-by-step explanation:

first for the easy one : the curve line is dotted, if the line points are NOT part of the solution. and it is solid, if the points are included.

you know what the curve line indicates ? it indicates the points for which there is equality.

so, if there is a ">=" or "<=" relation, then that includes equality, and the curve is solid.

if there is only a true inequality ("<", ">"), then the curve is dotted, as the equality is not included.

so, I how this is now really clear.

in our case here (I suspect it really looks like this)

y + 4x <= x² + 2

we have a "<=" sign, so, the curve is ..., well ? ... well ? ...

well ? ... well ? ... solid !

and we still treat inequalities as much as possible as regular equalities.

so,

y <= x² - 4x + 2 (after subtracting 4x from both sides).

and now you see it, right ?

all y values that are smaller or equal to the quadratic expression.

SMALLER ! so, BELOW the curve (as the smaller y values are represented by the lower part of the y-axis).

Answer: (a) 8    (b) 12

Step-by-step explanation:

Given : The number of different kinds of soups = 6

The number of different kinds of salad = 2

(a) If you are having either soup or salad, then the total number of choices you have :-

6+2=8

Hence, the total number of choices you have = 8

(b)  If you are having both soup and salad, then the number of choices you have :-

6\times2=12

Hence, the total number of choices you have = 12
