2x^2 + 28x + 98 =
2(x^2 + 14x + 49) =
2(x + 7)(x + 7) <==
By what is P i assume you mean what is the probability.
Well probability is always the specific group divided by the total
To find the total add all the marbles together
4 + 6 + 14 + 5 +8 = 37
Before we move on notice the question says that the marble is replaced after being chosen meaning the total stays the same for every pick
Red Marbles Probability:
red marbles/ total
6/37 or if you divide it out 0.162
Blue Marbles Probability:
blue marbles/total
8/37 or 0.216
Answer:
12
Step-by-step explanation:
the shapes are similar which means the sides are proportional, you can set up a ratio using the sides as 10/40 = 3/x
solving that gives you x =12
Divide 10 by 25, which would get you 4. Move the decimal over two to the left, because you wanted a percentage.
Jenny gave away 40% of the roses.
