Answer:
x = -1/9
Step-by-step explanation:
first let's think of x as 1x so than x^2 is basically 1x.
you bring down 8x + 1 = 0 so you have x + 8x + 1 = 0.
than you add x and 8x which equals 9x.
you bring the problem down one more time so 9x + 1 = 0.
you subtract 1 from each side so the 0 becomes because 0 - 1 is -1.
So than you bring the rest of the problem down 9x = -1
Last thing you do is divide 9 from both sides which x = -1/9.
The answer is 54 & 36, hope this helps.
Answer:
25. 9(2.50) + 9(4) = 58.5. The total cost of the folders and notebooks is $58.50.
26. 5(11.75 + 5) = 83.75. The total cost of the tickets and lunches is $83.75.

Answer: Formula For Factoring Trinomials (when a =1)
It's always easaier to understand a new concept by looking at a
specific example so you might want to do that first. This formula works
when 'a' is 1. [ In other words, we will use this approach whenever the
coefficient in from of x2 is 1.
1) identify a,b, and c in the trinomial ax2 + bx+c
2) write down all factor pairs of c
3) identify which factor pair from the previous step sums up to b
4) Substitute factor pairs into two binomials
Step-by-step explanation:
(x/6) + 4 = 15
-4 -4
x/6 = 11
x6 . x6
x=66
