What is the correct expansion of the binomial (x + y)^5

1 answer:

8 0

Ok you will multiply (x+y)(x+y) to get x2 + xy + y2, now multiply that times (x+y) to get x3+2x2y+2xy2+y3, now multiply that times (x+y) to get x4+3x3y+2x2y2+3xy3+y4, now multiply that times (x+y) to get you final answer which will be x5+4x4y+5x3y2+6x2y3+4xy4+y5

Hope this helped

Make sure you know the formula pertaining to the question.

1. c=2(pi)(r)
2. c=2(pi)(d)

r= radius
d= diameter
c= sircumference

So we are given that the circumference of a circle is 12.3pi and the radius is unknown.

So let's plug in the known values

**we use the formula with the radius, becuase we are looking for the radius.

c=2(pi)(r)
12.3(pi)=2(pi)(r)

divide each side by pi

12.3=2(r)

divide each side by 2

r=6.15 in.

Area = length × width

Her bedroom measures 12 feet by 14 feet. Therefore, the area of her bedroom would be

12 × 14 = 168 square feet.
