Answer: 11.66ft
Step-by-step explanation:
6squared=36+100=136
square root of 136= 11.66ft
I agree. Both of the equations come out to 2x^2+14x+20
(2x+10)(x+2)
Use the FOIL method
2x^2+4x+10x+20
Combine like terms
2x^2+14x+20
(2x+4)(x+5)
Use the FOIL method
2x^2+10x+4x+20
Combine like terms
2x^2+14x+20
Any equation in the form
Is a line. So, we only need to sample two points, and then connect them.
If we choose, for example, x=0 and x=3, we have
So, when x=0 then y=0, i.e. the line passes through the origin (0,0).
Similarly, when x=3 then y=2, i.e. the line passes through the point (3,2).
Connect these two points and you have the line.
4+21-18
25-18
7 is the correct answer
Total number of marbles in the bag is 28+49=77
Ratio of red in total can be written as:
49/77
We can simplify this by dividing both by 7.
Once we do that we have:
7/11
That means that the answer is A)
