OK. Concentrating only on the first log, here's how it works out:
log [ x · (6x + 1) ] = log (6x² + x) .
Now looking at the whole left side, it says
log (6x² + x) - log (x)
which is log [ (6x² + x) / x ]
= log (6x + 1).
So now we have
log (6x + 1) = 7
Raise 10 to the
power of each side: 6x + 1 = 10⁷
6x = 9,999,999
x = 9,999,999 / 6
= 1,666,666.5
This number works when you plug it into the original equation.
I'm sorry, but just now, I don't see where a second solution would come from.
Answer:
x = 14.4
Step-by-step explanation:
This is similar triangles where the large one is proportional to the smaller triangle inscribed inside it. Lay the 2 triangles out like so and the 30(hypotenuse) is proportional to 18. You can use the scale factor to find the "x" by doing: 24/1.66666666667(which is the scale factor you get from 30/18). This should give you 14.4.
Answer:
23.9
Step-by-step explanation:
His route from school to Rhianna's house to his house forms a triangle in which the sides are 7 miles and the hypotenuse is unknown. Solving using the Pythagorean theorem, we find the route from Rhianna's house back home is 7^2+7^2=x^2.
Rounding to the nearest tenth, we now know this route is 9.9 miles. Adding the total distances from each location, we get an answer of 7 + 7 + 9.9 = 23.9.
