Answer: P = 25n + 35
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(l +w)
P = 2((8.5n+9) + (4n +8.5))
P = 2(12.5n +17.5)
P = 25n + 35
-12 + 18 = 70 - 64 or(-12+18)+(6*12)-2

Answer:
11th number is 6
Step-by-step explanation:
60
D>0, there are 2 distinct real roots
Explanation:
3x2+6x−2=0
a=3,b=6,c=−2
The formula for discriminant is b2−4acSubstitute the given values.
b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots
