1/3 + 2/5 • 2/3
2 • 2 = 4
5 • 3 = 15
1/3 = 5/15
5/15 + 4/15 = 9/15 = 3/5
1/3 + 2/5 • 2/3 = 3/5
Answer:
x: length
y: wide
x = 3y and x*y =192
=> 3y^2 = 192
=> y = 8 => x =3x8 = 24
=> Perimeter = (x+y)*2 = (8+24)*2 = 64
The second and the third one because first is the same as 3 4/7 and 81=3^4
I’m pretty sure it is B
Hope I helped.
