Rachael is placing a protective cover on a glass case. The case is a cube, and the perimeter of one cube face is 56 inches. How many square inches of the protective covering does she need for the case?

336

Step-by-step explanation:

We know that a cube has 6 faces which means we can use this equation:

56 x 6 = 336

336 square inches is the answer.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

think about it deeply and passionately about this property

i am sorry
