Answer:x=0
Step-by-step explanation:
subtract 3 from both sides
3=3=x+3-5x-3
simplify
0=x-5x
switch sides
x-5x
add similar elements ; x-5x=-4x
-4x=0
divided both side by -4
-4x/-4 . = . 0/-4
=0
Answer:
x=7
Step-by-step explanation:
ln x +ln(x+1)=ln 56
ln x(x+1)=ln 56
so x(x+1)=56
x^2+x-56=0
(x+8)(x-7)=0
x= -8 or x=7
and lnx,x>0
so x=7
Answer:
C
Step-by-step explanation:
If a square has 4 sides and the perimeter is 12x + 52, you have to divide 12x + 52 by 4 to get the length of a single side
12x / 4 = 3x
52 / 4 = 13
3x + 13
