Answer:
a) 2x^4 + 8x^3 + x^2 + 3x
b) evaluate this polynomial at x = 10
Step-by-step explanation:
Hi!
a)
The product of a sum is the sum of the products, having said this:

b)
We can use the result from part a and consider x = 10.
First lets take the first polynomial

Knowing that every number (excepting probably 0, which could be undefined for some or 1 for others) to the power of 0 is one:

Which is the initial number
Now lets conisder the product of the polynomial times x and evaluate it at x=10:



We can now see that teh rule is treu because we can see the whole number as a sum of numbers from 0 to 9 multiplied by a power of 10, and when it is multiplied by 10, each power increases by one, and at the end, the final result is adding a zero at the end
Answer:
The 45th term is equal to -209.
Step-by-step explanation:
I got stuck on this question for six attempts. Therefore I started trying other methods. I started with a10=1 and then subtracted 6 to get a11=-5. I continued this process until I reached a45=-209
Sent a picture of the solution.
for perimeter you need to add, 15ft, 80ft, 30ft, 50ft, and 60ft which is 235 feet
for area you need to multiply 15ft times 80ft to get the area of the long verticle one which is 1200
then multiply 50ft times 30ft which is 1500
then add 1200 and 1500 which is 2700ft^2
