Answer:
I believe the answer is D: 300 inches
Step-by-step explanation:
This might be incorrect, but here's how I see the answer:
First I found the perimeter of one square.
2 + 3 = 5^2= 10
10 inches is the perimeter of one square.
Then, since there is 30 rectangles, and each perimeter is 10 inches long, then you would simply need to multiply the two numbers.
30 * 10 = 300 inches of red thread will be needed.
4(2x + 3) = 2(3x - 4)
8x + 12 = 6x - 8
8x - 6x = -8 - 12
2x = - 20
x = -20/2
x = -10......if u get a variable equal to a number, then there is 1 solution
if u would have ended up with 0 = 0 or 5 = 5...or something that is equal, then there would be infinite solutions.
if u would have ended up with 2 = 3, or 5 = 7...or something unequal, then there would have been no solution.
