bearing in mind that lines with an undefined slopes are vertical lines, Check the picture below.
The answer:
the main rules of the use of logarithm are
loga[a] = 1
loga[AxB] =loga[A] +loga[B] for all value positive of A and B
loga[A/B] = loga[A] - loga[B] for all value positive of A and B
in our case, <span>log8 4a (b-4/c4)
so it is equivalent to </span>log8 4a + <span>log8(b-4/c4)
and since </span>loga[A/B] = loga[A] l - oga[B] , log8(b-4/c4) =log8(b-4) - log8(c4)
the possible expression:
log8 4a (b-4/c4) = log8 4a + log8(b-4) - log8(c4)
Step-by-step explanation:
area=length x width
91=(x+2)(2x+3)
91=x^2+5x+6
x^2+5x-85=0
x=14.2 orx=-24.1
Answer: 20 degrees
Have a good day :)
