Answer:
12x + 4
Step-by-step explanation:
ok so a rectangle has 4 sides, 2 of which are called lengths, and 2 of which are widths.
length = 2x-3
width = 4x+5
the perimenter is the total of the 4 sides.
2(2x-3) = 4x-6 (the total for lengths)
2(4x+5) = 8x+10 (the total for widths)
add the 2 together:
12x+4
9/10 because that equals .9
Only multiplication and division don't change the ratio that made the order pairs in the bigger picture the triangle. Only one is not congruent. I'm about 90% sure I got it correct.
