The area of a square is found by squaring one of its sides, (a = s2). a certain square has an area of z2 + 18z + 81. factor the trinomial to find a side of the square.
a. side = z + 27
b. side = z + 18
c. side = z + 9

option c is correct.

side = z+9

Step-by-step explanation:

Area of a square(A) is given by:

where,

s is the side of the square.

As per the statement:

A certain square has an area of  

⇒

Substitute in [1] we have;

Taking square root both sides we have;

Using identity rule:

then;

⇒

Simplify:

or

s = z+9

Therefore,  a side of the square. is, z+9

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept
