Answer:
r = -1/2
Step-by-step explanation:
To find r, divide any number in the set by the previous number in the set and reduce the fraction if possible. Check multiple numbers to make sure r is consistent between all entries...
-200/400 = -1/2
100/-200 = -1/2
-50/100 = -1/2
So r = -1/2
First round 15.25 to 15.30 and round 4.85 to 4.90 and then add you get 21.20 no it is not reasonable and you round to the decimal ones
600inches<span>² because I am asuming that 40 is the botton base and 60 is both of the sides. </span>
Answer:
D. 1 and 20
Step-by-step explanation:
To solve the equation, factor the quadratic and set the factors equal to 0.
d^2 - 21d + 20 becomes (d-20)(d-1) since -1*-20 = 20 and -1+-20 = -21.
Set each equal to 0 and solve for x.
d-20 = 0 d = 20
d - 1 = 0 d = 1
