(x^2-3x+2)-1(3x^2-5x-1)=
x^2-3x+2-3x^2+5x+1=
x^2-3x^2-3x+5x+2+1=
-2x^2+2x+3
There are two ways (of many) to do this
Method 1:
47/x = 82/73.8
47*73.8 = 82x
3468.6 = 82x
82x = 3468.6
x = 3468.6/82
x = 42.3
---------------------------------
Method 2:
47/x = 92/82.8
47*82.8 = 92x
3891.6 = 92x
92x = 3891.6
x = 3891.6/92
x = 42.3
---------------------------------
Either way, the answer is 42.3 meters
Answer:
60 × 50 = 3000
7 × 50 = 350
60 × 4 = 240
7 × 4 = 28
3000 + 350 + 240 + 28 =3618
54 × 67 = 3618
