Circumference of a circle is 2(pi)(r)
2(3.14)(7)= 43.96
So the answer is B
Answer:
if you are dividing 299.96 If you are multiplying 26.99
Step-by-step explanation:
If you are dividing: Factor the numerator and denominator and cancel the common factors.
If you are multiplying: Simplify the expression.
Answer:
Step-by-step explanation:
(a+b)^2=a^(2)+2ab+b^(2)
(a-b)^2=a^(2)-2ab+b^(2)
13)
(x+2)^(2)-(x-1)^2
x^(2)+4x+4-(x^(2)-2x+1)
x^(2)+4x+4-x^(2)+2x-1
6x+3
15)
(x+5)^(2)-(x+1)^2
x^(2)+10x+25-(x^(2)+2x+1)
x^(2)+10x+25-x^(2)-2x-1
8x+24
7 will never equal 8 so there is no solution. so i think it is C
