Answer:
8, 10
Step-by-step explanation:
Multiplying the equation by the product of the denominators, we have ...
40(x+2) +40x = 9x(x+2)
80x +80 = 9x^2 +18x . . . . eliminate parentheses
9x^2 -62x -80 = 0 . . . . . . put in standard form
9x^2 -72x +10x -80 = 0 . . . prepare to factor by grouping
9x(x -8) +10(x -8) = 0 . . . . . factor pairs of terms
(9x +10)(x -8) = 0
Solutions are ...
x = -10/9 and x = 8
The integers are 8 and 10.

I find a graphing calculator to be a nice tool for solving these. It finds zeros easily, so writing the equation so it equals zero is a useful first step.
The ratio is 2:5 yep
hope it helps how do you know?
Hi Timothy,
1. Write a rule for the sequence.
8, -1, -10, -19...
A. Start with 8 and add -9 repeatedly
B. star with -9 and add 8 repeatedly
C. start with 8 and add 9 repeatedly
D. start with 8 and subtract -9 repeatedly---
Answer - So you have to start with -9 then keep subtracting 9. Thats what I think the answer is but the answer is not stated in the question. Let me know on what that is. The closest answer is probably either B or D.
2. find the next three terms of the sequence.
-6, -24, -96, -384
1) -768, -1536 , -3072
2) -768, -3072, -12288
3) -1536, -6144 , -24567
4) -1536, -9216, -36864
The rule is multiplying by 4!
So the correct answer is 3) -1536, -6144 , -24567
D. Issuing Treasury bonds and other goverment-backed securities.
-Hope this helps :)
answer:
600 tablets in 33/4
Step-by-step explanation:
