Step-by-step explanation:
The perimeter of a triangle is calculated by adding all three side lengths together
That means x + 3 + x + 4 + x + 1 = 17 add the like terms
3x + 8 = 17
3x = 9
x = 3
BC = x + 3 ➡ 6
CD = x + 4 ➡ 7
BD = x + 1 ➡ 4

Answer:
Sum of the sequence (Sn) = 33,859
Step-by-step explanation:
Given:
Sequence = 685+678+671+664+...+6
Find:
Sum of the sequence (Sn)
Computation:
a = 685
d = 678 - 985 = -7
an = 6
an = a+(n-1)d
6 = 685+(n-1)(-7)
-679 = (n-1)(-7)
97 = n-1
n = 98
So,
Sum of the sequence (Sn) = (n/2)[a+an]
Sum of the sequence (Sn) = (98/2)[685+6]
Sum of the sequence (Sn) = (49)(691)
Sum of the sequence (Sn) = 33,859
Answer:
x^2-12x+27
Step-by-step explanation:
(x-3)(x-9)=x^2-3x-9x+27=x^2-12x+27
