Answer:
A factor is a number that when its multiplied with another number, gives a product of a given number. Example: The factors of 21 are 7,3,1 and 21. A multiple is a number that can be divided by another number a certain amount of times evenly (without a remainder). Example: Some multiples of 4 are: 8, 12, 16, and 20.
For the same reasons as the last problem...
s(n)=20(1-(1/2)^n)/(1-1/2)
s(n)=40(1-(1/2)^n)
But this time we are not starting at one so we must subtract the sum of s(2) from the sum of s(12) so:
40((1-(1/2)^12-(1-(1/2)^2)
40(0.249755859375)
≈9.99 (to nearest one-thousandth)
I got -4/3 or 1.333333333 as my answer.
Hope my answer is correct ☺

Answer:
Step-by-step explanation:
1:A=b times h as its a parallelogram:21 times 33= 63
2:A=a+b
/2 h as its a trapezium= 91
3:A=πr squared=26.42
4:A=hb/2=27 times 6/2=216
