F and D is the answer
hope this helps
have a good day
An equivalent fraction in higher terms is 9/12 because you must multiply the top by 3 because you multiplied the bottom by 3
2) Larger triangle is twice as large as the smaller one so x is 16
3) 16/12.8= 1.25 (This is the scale factor)
for y: 10/1.25=8
for x: 30/1.25=16
4) 8/6.4=1.25 (Scale factor)
for y: 14/1.25=11.2
for x: 15/1.25= 12
5) 22.5/9= 2.5 (scale factor)
for x: 12x2.5=30
for y: 35/2.5= 14
6) No because the scale factor is 2 but 14/8 does not equal to 2
Using Pythagoras:
12^2+5^2= 144+25=169
√169= 13
