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
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
The correct answer is B because she needs to know how many row are there to get the final total of chairs in the meeting hall.
