Answer:
x^10
Step-by-step explanation:
x^10
This is a proportion problem because the problem stated that the two team pennants are similar.
Pennant 1 = base = 18 in ; length = 9 inches
Pennant 2 = base = 6 in ; length = x ?
9/18 = x/6
9*6 = 18x
54 = 18x
54/18 = x
3 = x
The length of the side of the smaller pennant is 3 inches.

A product means multiplication, so...
(x * -2) +8 = -4
-2x + 8 = -4
To isolate the x, we have a couple of different ways, but the easier for now would be to start off by moving the 8 to the other side via subtracting both sides by 8:
-2x + 8 - 8 = -4 - 8
-2x = -12
Next, we divide both sides by -2
-2x / -2 = -12 / -2
x = 6
Y + 2x = 3....put this in y = mx + b form by subtracting 2x from both sides
y = -2x + 3
so u have a slope of -2 and a y int of 3 or (0,3)
ur x int can be found by subbing in 0 for y and solving for x
y + 2x = 3
0 + 2x = 3
2x = 3
x = 3/2 or 1.5....so ur x int is (1.5,0)
so go ahead and plot ur intercepts (1.5,0) and (0,3).....and since u have a slope of -2, start at (0,3)....come down 2 spaces, then go right 1 space....plot that...then down 2 and to the right 1...plot that...keep doing this and u should cross the x axis at (1.5,0)....then connect ur plotted points and u have ur line.
