Answer:
Step-by-step explanation:
As it is a second order equation, it means that it has two possible answers and they are and
.
The famous quadratic formula for solving any second order equation is the following:
Where a is the coefficient of , b is the coefficient of x, and c is the free term. In other words,
as the equation should be in the following form:
Therefore the possible answer should be the following,
by dividing the numerator and denominator by 2, we can deduce the following,
7x+2
Step-by-step explanation:
add all the sides of the pentagon and make it equal to the perimeter of the square which is 4y
sides of the pentagon are
5x+3
2x+3
7x+4
9x-10
5x+8
28x+8=4y
7x+2 = y
7x+2 = answer

another way :
in a standardized test you may want to use real numbers
make x equal a prime number like 3
so then the sides are
18
9
25
17
23
=
92
then divide by 4
23
then divide by 3
which is 7 remainder of 2
which is
7x+2
