Two terms that add to 22 and multiply to give 21 are 21 and 1. Replace 22x with 22x and x.
7x^2 + 21x + x + 3
7x (x + 3) + 1 (x + 3)
(7x + 1) (x + 3)
Answer:
(20). 256^0 = 1
(21). 10^2 = 100
(22). 4^4 = 256
(23). 3^5 = 243
Step-by-step explanation:
(20). 256^0 = 1
(21). 10^2 = 10*10 = 100
(22). 4^4 = 4*4*4*4 = 256
(23). 3^5 = 3*3*3*3*3 = 243
Answer:
Step-by-step explanation:
x can really be anything because you did not include the sum for both expressions. so im not sure. its best to wait for someone else to answer. :/
The nth term of an arithmetic sequence is given as:
Where
a_1 is first term
d is common difference (diff between terms)
n is the term number
Now,
in the sequence, we see
First Term = 2
Common DIff = 24 - 2 = 22 and 46 - 24 = 22, so Common Difference = 22
So, the general formula is:
The best thing to do is to rewrite the fractions as decimals
-2/3 is approx. equal to -0.6666667
So a little past half way (to the left) between -1 and 0
1 1/5 is 1.5 so that is right between 1 and 2
Hope this helps :)
