2: terms/4w, -5, 6, 2x, 7, -19 coefficients/4w, 2x
Answer:
B; The second answer
Step-by-step explanation:
The question is asking about the associative property of addition. This involves the rearranging of the parenthesis. If you were to solve the given equation, and solve the the answer, then you will get the same answer. In this property, it says that you will get the same result if you were to move/switch the parenthesis from the values; This means that order doesn't matter.
Answer:
32
Step-by-step explanation:
if he has 32 and brought 8 thats a total of 40 because 32+8=40, then if the fire burned half of the boxes 40/2 = 20
Perimeter of the shape is 2(AB) + 2(BC)
AB = sqrt((7 - 5)^2 + (3 - 5)^2) = sqrt(2^2 + (-2)^2) = sqrt(4 + 4) = sqrt(8) = 2.83
BC = sqrt((3 - 7)^2 + (0 - 3)^2) = sqrt((-4)^2 + (-3)^2) = sqrt(16 + 9) = sqrt(25) = 5
Perimeter = 2(AB) + 2(BC) = 2(2.83) + 2(5) = 5.66 + 10 = 15.7
