Answer:

Step-by-step explanation:
The given equation is

We take logarithm of both sides to base 10.


We expand the brackets to get;

Group similar terms;




To the nearest hundredth.

39x^3 = 13*3*x*x*x
-6x^2 = 2*3*x*x*-1
-3x = 3*x*-1
so in all these factorizations, 3*x is common. so 3x is the common factor.
by seperating the common factor,
3x(13x^2 - 2x-1)
will be the factorization.
xy + 5x - 5y - 25
=x (y+5) -5 (y+5)
=(x-5) (y+5)
hope I helped ya!!!
Sorry, I didn't quite understand the question here is a clear one, it was made by me personally in the geo-gebra application
Answer:
12
Step-by-step explanation:
The proportion is equal to 
We can simplify the right side by dividing by 7/7 to get the right side equal to 6/5. Now we can cross-multiply to get

Dividing both sides by 5, we have the answer as

Hello,
y²+4y+4=7
==>(y+2)²-7=0
==>(y+2-√7)(y+2+√7)=0
==>y=-2+√7 or y=-2-√7
