PLease

Step-by-step explanation:

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:

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

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
