Answer:

Step-by-step explanation:

if we put the ratios as fractions, we would get 2/1, or just 2, and 1 4/5. these are not equivalent, so the ratios are not equivalent either.

Answer:

No.

Step-by-step explanation:

2:1 has multiple equivalents, for example:

2:1

4:2

6:3

5:10

...

The 1st number will always be double of the 2nd number,

2 is double of 1

4 is double of 2

6 is double of 3

...

9 is not double of 5.

Answer:

16 ft

Step-by-step explanation:

Let the width of the rectangle be x ft

Therefore, length = (x + 2) ft

Area of the rectangle = 15 square ft

$x(x + 2) = 15 \\ \\ {x}^{2} + 2x = 15 \\ \\ {x}^{2} + 2x - 15 = 0 \\ \\ {x}^{2} + 5x - 3x - 15 = 0 \\ \\ x(x + 5) - 3(x + 5) = 0 \\ \\ (x + 5)(x - 3) = 0 \\ \\ x + 5 = 0 \: or \: \: x - 3 = 0 \\ \\ x = - 5 \: \: or \: \: x = 3 \\ \\ \because \: x \: can \: not \: be \: - ve \\ \\ \therefore \: x = 3 \\ \\ \implies \: x + 2 = 3 + 2 = 5 \\ \\ perimeter \: of \: rectngle \\ = 2(5 + 3) \\ = 2 \times 5 \\ = 16 \: ft$
