Answer:
240
Step-by-step explanation:
So let the first side be x. So the next side is 3x and the last side is (3x +60) . Add all 3 sides and set equal to 480. So x + 3x + (3x +60)= 480. Now do the Algebra. So 7x + 60 = 480. Subtracting 60 we get 7x = 420 so x= 60. You are asked to ffg ind the length of the longest side so 3(60) + 60 = 240.
Answer:
a1 = 4
a2= -2
a3 = -8
a4= -14
a5= -20
Step-by-step explanation:
a12= a1 + 11d
-62 = 4 + 11d
-62-4 = 11d
-66= 11d
d =
= -6
a1 = 4
a2 = 4 - 6 = -2
a3 = 4 - (6×2) = -8
a4 = 4 - (6×3) = -14
a5 = 4 - (6×4) = -20
