Let me know if this helps :)
Answer:
g = 36
Step-by-step explanation:
We have the equation
+ 7 =19
Subtract 7 from both sides:
= 19 - 7 = 12
= 12
Now, multiply by 3 to both sides: 3 ×
= 3 × 12
g = 36
Answer:
<h2>see below</h2>
Step-by-step explanation:
<h3>
Question-6:</h3>
we are given a equation

to solve so
recall logarithm multiplication law:

simplify multiplication:

remember 
so

cancel out
from both sides:

simplify squares:

move left hand side expression to right hand side and change its sign:
since we are moving left hand side expression to right hand side there'll be only 0 left in the left hand side

rewrite it to standard form i.e ax²+bx+c=0

rewrite -6x as 2x-8x:

factor out x and 8:

group:



<h3>Question-7:</h3>
move left hand side log to right hand side:

use mutilation logarithm rule;

so

cancel out log from both sides:

make it standard form:

factor:

so
