Answer: Is your question "What is the length of each side?"
Let x = the length of the second side
Let x - 5 = the length of the first side
Let (x - 5) - 2 = the length of the third side
P = a + b + c
x + x - 5 + x - 7 = 42
3x - 12 = 42
3x = 54
x = 18 yards
x - 5 = 13 yards
x - 7 = 11 yards

Graph the equation on a graph then the x intercept will be shown, the x intercept is -2.
Answer:
29
Just replace n by 8 ===> C(8) = -6+5(8-1) = - 6 + 5x7 = -6+35 = 29
Step-by-step explanation:
We have been given a sequence formula. We are asked to find the 8th term of our given sequence.
We know that an arithmetic sequence is in form A_n=a_1+(n-1)d, where,
A_n=\text{ nth term of sequence},
A_1=\text{ 1st term of sequence},
n = Number of terms in sequence,
d = Common difference.
To find the 8th term of our given sequence, we will substitute n=8 in our given formula.
c(n)=-6+5(n-1)
c(8)=-6+5(8-1)
c(8)=-6+5(7)
c(8)=-6+35
