Answer:
Step-by-step explanation:
The simple answer is that logs cannot be negative and if you insert a 2 where the x is located you get a negative. Logs have to be >= 0
[text]log_5 (3x-10) = log_5 (-4)[tex]
It all has to do with logs being tied to exponents and exponents being tied to logs. Actually an inverse of an exponent is a log.
It's too hard for me to show all the work, but you can find a common denominator in 8.
Change 3/4 to 6/8 and -3/2 to -12/8.
Now that all the fractions have the same denominator, you can multiply the whole problem by 8 and cancel out all denominators.
You are left with 6=3x-12
Add 12 to 6 and cancel out on the right side.
18=3x
Divide by 18 by 3
x=6
<span>We have lateral faces that are rectangles and 2 congruent polygons that are bases. This must be 3-dimensional solid figure - quadrilateral prism. If those 2 bases are squares then it is a rectangular prism, but the bases also can be 2 rhombuses. Answer: Quadrilateral prism.</span><span />
