Answer:

D. 27x^3y^3

Step-by-step explanation:

The exponent at the end that is above and outside the parenthesis of the whole thing, needs to be passed out to each piece inside the parenthesis. See image. 3^3 is 27 and a power to a power, you multiply the exponents. See image.

Answer:

Trapezoid

Step-by-step explanation:

perpendicular: They are perpendicular due to the fact they cross at right angles to each other. Another true instance of perpendicular lines we will see in nature is a football field. All four corners of a football field are perpendicular to every other.

In the trapezoid attached there aren't any perpendicular sides. A and B are both obtuse angles in this diagram, and C and D are both acute angles. However, now not all trapezoids appear like this. ... Definition B: A trapezoid is any quadrilateral with at the least one pair of parallel sides.

Answer:

849.24 cm²

Step-by-step explanation:

we know it is a cube so to find the surface area of each square you do

12x12=144 and there are 5 sides so 144x5=720

We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle

Now using pythagorus you would do a²+b²=c²

15²+6²=c²

225+36=c²

√261=√c²

16.15=c this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24

now add 720+129.24=849.24 cm²

A probability experiment has two steps. There are two possible results for the first step, call them "A" and "B". If the result

denis23 [38]

Answer:

Step-by-step explanation:

Two possible results A and B

If the result for the first step was "A", then there would be 4 possible results for the second step.

Let us say the 4 possible results are 1,2 ,3,4

So, Possible outcomes for this case = {A1,A2,A3,A4} =4

If the result for the first step was "B", then there would be 16 possible results for the second step.

Let us say the 16 possible results are 1,2 ,3,4,....,16

So, Possible outcomes for this case = {B1,B2,B3,B4,....,B16} =16

So, Total possible outcomes = 16+4 = 20

Hence there are 20 possible outcomes for this experiment.
