What is the next value 4d 7g 10j 13
bearhunter [10]
13m 16p

Add three to every number next as well as move up three letters.

For example:
1A is the starting point.
To get from 1A to 4D you add three.

1 + 3 = 4
A to get to D is three letters up.
A b c D

Same thing for 4D to get to 7G.

4 +3 = 7
D to get to G
D e f G

Your answer:
I'm not sure if you wanted me to find the letter of the equation or the actual next part. On your question you have just 13 up there, no letter so if youre trying to find the letter (13m) is your answer.

If you're trying to find the next equation to the puzzle (16p) is your answer.

Hope this helped!:)

Is (x-1) a factor of 2x3 - 15x2 + 22x + 15
Advocard [28]

Answer:

Step-by-step explanation:

If x - 1 is a factor of the cubic, then 1 should result in 0 when you put it in the cubic for x. Does it?

f(1) = 2(1)^3 - 15(1)^2 + 22(1) + 15

f(1) = 2 - 15 + 22 + 15

f(1)= 24.

No the result is not zero. So x - 1 is not a factor.

However there must be something that makes this cubic go to zero. The easiest way to find it is to graph it.

The numbers that do make this zero are -0.5, 3, 5

Which mean that the factors are (2x+1)(x-3)(x - 5)
