Which special case is represented by?

A. the difference of two squares

Step-by-step explanation:

we are given

we can write

so, we can see that

x^2 is square

11^2 is also square

so,

It means that

two squares are subtracted

so, it is difference of two squares

so,

A. the difference of two squares

b. x + 1

step-by-step explanation:

i'am smart

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
