Answer:
solve simultaneously
start by labeling them equation 1 and 2 then choose whether you want to make x or y the subject from knew of the equations
a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number
might be confusing so here's an example
1,2,4,8,16
each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio
formula for geometric sequence is

where
is nth term
is first term
r is teh common ratio
n=which term
in our example
1,3, 9, 27, 81
each term is being multiplied by 3 so it is a geometric sequence and thus r=3
also first term is 1 so 
so the formula is
or in function notation 
Answer:
Option C. 144 square inches is the correct answer.
Step-by-step explanation:
We have been given a square with one side with a measurement of 1 foot and we have to calculate the area in square inches.
First we know that 1 foot of length = 12 inches on scale
Therefore side of the square is 12 inches
Now the area of the square will be = (Side×Side) = (Side)²
= (12)² = 144 square inches.
So the area of the square will be 144 square inches.
