Answer:
33/8 or 4 1/8 simplified.
Answer:
yes
Step-by-step explanation:
If all contributors to the distribution are doubled, the value of any particular item in the distribution will be double what it was. That is, it will be different.
Rearrange to: x^2 + 18x - 25 = 0
Then factorise (I like to do it by completing the square):
(x + 9)^2 -81 -25 = 0
(x + 9)^2 = 106
x + 9 = sqrt(106)
The sol'ns are:
x = -9 + and - sqrt(106)
