so the nth term is really the 10th term, and we know that's 57, thus
so, that's the common difference... .so you'd surely know what the 3rd term is, notice the first one is 102.
Good evening ,

Answer:
w=6.5in
___________________
Step-by-step explanation:
L : length
w : width
p : perimeter
38=2L+2w
38 =2(w+6)+2w
38 = 4w+12
38-12=4w
26=4w
26/4=w
w=6.5 in.

Perimeter is the sum of all sides of a polygon. For this case, the perimeter is expressed as: P=a+b+c. It has been said that the longest side is twice that of the shortest side. Let's assume that a is the longest side and b is the shortest side. So, the equation for the shortest side is,
6.2 = 2c
c = 3.1
14.5 = 6.2 + 3.1 + b
<span>14.5 = 9.3 +b</span>
Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.
