If a+b+c=8 and x+y=7 what is -8y-2c-2b-8x-2a
sergey [27]

Answer:

-40

Step-by-step explanation:

Try rearranging and factoring -8y-2c-2b-8x-2a:

This is equal to -8(x + y) -2(a + b + c).

Since x + y = 7, we have:

                            -8(7) -2(a + b + c)

and since a + b + c = 8, we end up with:

                             -56 - 2(8), or

                               -56 - 16    = -40

Please help you have to find the sides and stuff help plssss
oksano4ka [1.4K]

Answer:

A) The side is 14 cm

B) The total distance around the whoole board is 56 cm

Step-by-step explanation:

So we know its a square.

A square is all equal sides

We got the area which is 196

So we know area of a square is L*W or S^2

And since all sides are equal we can square root 196

That would give you 14

So we know each side is 14

Part B is just perimeter, there are 4 equal sides so we can just multiply 14*4 which is 56.

CHECK:

So we want to check the sides are equal

Each side is 14

and area is 196

14*14=196

So its true
