SOLUTION
The given equation is
From the given graph, one of the solution of the equation is
Since x=4 is a solution to the equation it follows that x-4 is a factor
The given equatin can be simplified as
Therefefore other solutions are
The law of cosines states that:
c^2=a^2+b^2-2abcosC
You already have all the values for the variables with the exception of x so:
x^2=25+100-100cos60
x=√(125-100cos60)
x=√75
x≈8.66 to nearest one-hundredth...
Hi there!
The correct answer is 6.25 times.
This is how you get there:
1) First off, you are going to need to have the same unit (either cm or mm). I used millimeters for this problem. 25cm=250mm
2) This next part is very easy to get wrong. You need to figure out what you are dividing, and by what. Simply look at the problem. <span><em>"How much longer is the guinea pig than her fish?" </em>This shows what numbers you should be getting. The guinea pig is 250mm long, where the fish is only 40. This means that her guinea pig should be larger. 250÷40=6.25
If you did this problem the other way, you would've ended up with .16. If you put the sizes into perspective, you will notice that this is highly unlikely.
I hope that I have been able to simplify this problem for you!

Answer:
x=4
Step-by-step explanation:
3(3x+2)=7(x+2) Cross product
9x+6=7x+14 Solve for x
9x-7x=14-6
2x=8
x=8/2
x=4
Your answers are (5,12) (4,9) and (6,15)
These are all correct I jost took the quiz and got them all right:)
Please let me know if you need help with any other part of this quiz
I'll answer them to the best of my knowledge!
