Answer:
x=13
Step-by-step explanation:
According to the question
3x+5x-14=90
8x-14=90
8x=90+14
8x=104
x=104/8
x=13
Sorry a bit messy, with a ratio of 2:5:1, that means 5 would be the longest and your longest piece is 125, diving 125 by 5 gets you 25 cm, this is also your shortest piece since 1x25=25
32 is the correct answer :)
The answer is for 1-y=4
2- (2,10) (-2, -25) (-1, 1/5)
The answer is D because if you get the same answers from each shape that is congruent
