Area of a square is just length times width, so the area is 3x3= 9 square inches. It is super important to remember that when you do area, the units are squared when you write your answer. You could also write it 9 in^2

In how many ways can a photographer at a wedding arrange six people in a row, including the bride and groom, if a) the bride mus

ELEN [110]

Answer: a) 240, b) 480, c) 360

Step-by-step explanation:

Since we have given that

Number of people = 6

Number of bride and groom = 2

So, remaining people = 6-2 = 4

So, using the fundamental theorem of counting

remaining people can be arranged in

$4!=4\times 3\times 2\times 1=24$

Since bride has 5 positions to stand and grooms too has 5 positions to stand.

so, Number of positions for both bride and groom = 5+5=10

So, a) the bride must be next to the groom?

Number of ways = $24\times 10=240$

b) the bride is not next to the groom?

Total number of ways would be

$6!=6\times 5\times 4\times 3\times 2=720$

So, Number of ways that the bride is not next to the groom is

$720-240=480$

c) the bride is positioned somewhere to the left of the groom?

If Groom is in second position, bride has 1 ways to stand

If Groom is in third position , bride has 2 ways to stand

If Groom is in fourth position, bride has 3 ways to stand

If Groom is in fifth position, bride has 4 ways to stand

If Groom is in sixth position, bride has 5 ways to stand.

So, Number of ways to stand = 1+2+3+4+5=15

So, the total number of ways bride is positioned somewhere to the left of the groom is given by

$24\times 15=360$

Hence, a) 240, b) 480, c) 360

What is (c+d) to the power of 3

goblinko [34]

Answer:

c³ + cd³ + 3c²d + 3cd²

Step-by-step explanation:

(c+d)^3 is worded as c plus d quantity cubed which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.

(c+d)(c+d)(c+d)

You can only multiply 2 at a time so do the first two then the result and the third one.

Distribute everything in one quantity to the other so c*c = c^2 and c*d = cd

= (c^2 + 2cd + d^2)(c+d)

= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3

Combine like terms

= c³ + 3c²d + 3cd² + cd³
