Answer:
-149
Step-by-step explanation:
=-11 + (n - 1)(-3)
by observation
when n = 0, 
= 1st term
when n = 1, 
= 2nd term
.....
when n = x, 
= (x+1)th term
hence if we want to find the 48th term, n = 48 - 1 = 47
when n = 47, 
= 48th term
= -11 + (47-1)(-3)
= -11 + 46(-3)
= - 11 - 138
= -149
Answer: Carlo is incorrect
Step-by-step explanation:
3000/(2+3) = 600 (each ratio)
2:3 = 2(600):3(600) = 1200:1800
1200/6 = 200 small boxes
1800/20 = 90 large boxes
290 boxes altogether (large and small)
(large boxes/boxes altogether)x100
(90/290)x100 = 31%
31%>30%
Therefore Carlo is incorrect
Answer:
CD is equal to 3.2 m
Perimeter is equal to 37.5 m
Lets quickly run through the prime numbers and see what it is not divisible by
39 is not divisible by 2
39 IS divisible by 3
So lets stop right here.
What is 39 divided by 3? 13 !
And 13 is a prime number too!
So that is all we can do.
So prime factorization of 39 is <u>3 x 13</u><u><em /></u>
