1. 8r + 4 = 10 + 2r
-4 -4
8r = 6 + 2r
-2r -2r
6r = 6
R= 1
2. -2(x + 3) = 4x - 3
-2x - 6 = 4x - 3
+3 +3
-2x -3 = 4x

-1/2 = x
3. 5 + 3(q - 4) = 2(q + 1)
5 + 3q - 12 = 2q + 2
-7 + 3q = 2q + 2
+7 +7
3q = 2q + 9
-2q -2q
Q = 9
4. 7x - 4 = -2x + 1 + 9x - 5
7x - 4 = 7x - 4

5. 8x + 6 - 9x = 2 - x -15
-x +6 = - 13 - x

K= 2
The square is doubled so the scale factor (k) is 2
Answer:
It all comes down to simplifying it to inches and price so id 18 in” is 0.89 cent’s thats every inch of that 18 is about 4 cents a in” and a $1.89 3 feet is about 5 cent’s
Step-by-step explanation:
So is the first would be a better deal because it is one cent cheaper!
Answer:
Let width = l
Therefore, length = 3l
Perimeter = 2(l+b)
48 = 2(l+3l)
48 = 2× 4l
48 = 8l
8l = 48
l = 48/8
l = 6
Width = 6
Therefore, length = 3×6
= 18
Area = l×b
= 18×6
= 108
