Answer: C is about 100.53
Explanation:
C=2πr
C=2(3.14)(16)
C is about 100.53
Answer:
The bags would weigh 27lbs. multiply 4 1/2 and6 and you get 27lbs.
Set each binomial equal to zero and solve for your variable.
k + 1 = 0
Subtract 1 from both sides.
k + 1 - 1 = 0 - 1
Combine like terms
k + 0 = - 1
k = - 1
Same thing for the second binomial.
k + 5 = 0
k + 5 - 5 = 0 - 5
k + 0 = - 5
k = - 5
Your equation then has two solutions:
k = - 5, - 1
Answer:
