x - 4 squared provides 2 real zeros that are the same. These two are not distinct.
The other two come from x^2 - 7x + 10 which has a discriminate of
sqrt(7^2 - 4*1*10) = sqrt(9) = +/- 3 leading to something real and different.

Since Megan's chain is only 400 cm long, Mason's chain is longer by 79 cm.
Answer:
C(n) = 12 + 1.5(n – 1)
Step-by-step explanation:
Answer:
$1057.3
Step-by-step explanation:
First we'll find the Interest no. 1, which is simple interest, assuming the time 1 year:
S.I= PRT/100
S.I= 780*5.2*1/100
S.I=$40.56
Now we'll find interest no.2, which is compound interest, time is 6 years, Principal amount (780) will remain the same as well as the rate thus (putting in the formula of compound interest- annual-
):

A= $1057.3
Answer: C
4x7*2-25
4x49-25
196-25
= 171
