Step-by-step explanation:

The equation have in both sides expressions and

Therefore, the system of two equations

has the solution (x,y), where x is the solution of the equation above.

ANSWER

{

EXPLANATION

The given equation is

To find the system of equations, we just have to equate each side of the equation to y and form two different equations.

The left sides gives one equation,

The right side also gives,

Hence the correct choice is A

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
