If the two shapes at the right are similar, calculate the value of x

So we can see that these are similar shapes. So we can get a ratio for this'

21:51 is our ratio now we just need to compare to our second ratio

2x+3:34. So now we just need to get our multiplier which will be 34/51 because we're getting smaller. So we just need to multiply it by 21

21*34/51 = 14. So now we know that 14 = 2x+3

14 = 2x+3. Do simple algebra and get x = 11/2.

c. (3,2,6) is the answer.

the answer is b.)

< 1=< 2
