Answer:
The terms are 2, 6 and 12
The sum is 20
Step-by-step explanation:
n n + 1 n(n+1)
-- ------- ---------
1 2 1 x 2 = 2
2 3 2 x 3 = 6
3 4 3 x 4 = 12
The terms are 2, 6 and 12
The sum is 2 + 6 + 12 = 20
Answer: 69.6 Hope That helps!
Step-by-step explanation:
Answer:
the answer would be 270
Step-by-step explanation:
i can explain later:
since x = 5, you plug it in f = 4x +7, and you get f = 27 and since 1/2x is in the denominator, it will flip over and become 2x. 2x is 10, so you multiply f by g and get 270 which is if f/g(5) is the question.
2:3
Since 18 ➗ 2 = 9 then 9 ✖️ 3 = 27
Therefore it would be 2:3
The second one would be 4:1
60 ➗ 4 = 15 and since 15 is the opposing number that is the simplest it can go for this problem
Therefore it is 4:1
