U would by making 3/30 and dividing it all by 3
Surface area o fthe ball = 4 * 3.14 * radius^2
if diameter = 1.680 then radius = 1/2 * 1.680 = 0.84
so surface area = 4 * 3.14 * 0.84^2 = 8.862
Answer: The expression, 8 x 54, may also be expressed as 8 x 50 + 8 x 4 because by factoring the 8,
8 x (50 + 4) = 8 x 54
Further, it can also be expressed as,
8 x 60 - 8 x 6
because,
8 x (60 - 6) = 8 x 54
Step-by-step explanation:
Answer:x^2-y^2
Step-by-step explanation:
(x+y)(x-y) = x^2 -xy +xy -y^2 so it becomes x^2-y^2
The answer is A
because there is no other answer
