Please help me asap?!? test is past due :( Find the missing side lengths using your notes on the 45-45-90 and 30-60-90 special triangles.

It says that there was an error with my answer, but I don't know what, so I screenshotted what I typed and attached them as 4 images below:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
