Product is multiplication:
x * (x+2) = 201
x^2 +2x = 120
x^2 + 2x -120 = 0
(x+12) (x-10) = 0
x = -12 and x = 10
-12 x -1 = 12
the 2 numbers are 10 and 12
Answer:
4x
Step-by-step explanation:
Let the number of Tina's stickers = x
So, Bob will have 4 times as many as Tina's = 4x stickers

Answer: The concentration of X is
and the concentration of Y is
.
Step-by-step explanation:
Since we have given that
At 272 nm, absorbance = 0.215
At 327 nm, absorbance = 0.191
As we have given that
Compound X Compound Y
272 16400 3870
327 3990 6420
So, our equations becomes

By solving these two equations, we get that

Hence, the concentration of X is
and the concentration of Y is
.
