The answer to this would be A: -9/10. Hope this helps!
Answer:
x = 4
which agrees with the third listed answer among the given options
Step-by-step explanation:
We can re-write the logarithmic equation using the properties of logarithms:

Therefore, the arguments of the log functions must also be equal (and we can solve for "x" by noticing that this expression is the perfect square of a binomial:

and for this equation to verify, x must be 4
All four sides of a square are equal.
So if BC is 10, then AC is also 10.
Harrison is correct because the 305 in the actual problem is greater than the 300 in the estimate and 57872 is less than 60000. Harrison arrived at his prediction by rounding to the nearest ten thousand and nearest hundred.
-13+3b = -5-b
4b -13 = -5
4b = 8
b= 2
