Answer:
x=3
Step-by-step explanation:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
3x(x+1) = 4x(x)
Divide each side by x
3x(x+1)/x = 4x(x)/x
3(x+1) = 4x
Distribute
3x+3 = 4x
Subtract 3x
3x+3-3x= 4x-3x
3 =x
Answer: There would be about 6 or 7 silk fibers per 300 yard length of silk fiber.
The problem states that each thread is made of about 3 to 10 silk fibers. The the problem as for a reasonable estimation of the number of silk fibers. It would be safe to assume that a reasonable estimation would be the average (or mean) of 3 to 10.
(3 + 10) / 2 = 6.5
Since 6.5 is the average, we could use 6 or 7 as a reasonable estimation.

Answer:
Area of triangle = 144 sq.in
Area of rectangle = 312 sq.in
Area of whole figure = 456 sq.in
Step-by-step explanation:
area of truangle =
- 1/2 × 24 × 12
- 12 × 12
- 144
area of rectangle =
area of whole fig. = 312 + 144 = 456 sq.in
