Answer:
13.
Step-by-step explanation:
3x+1
x=4
Substitute x for 4
So, that would be 3*4+1
Now we multiply 3 and 4 to get 12. Then we add in the 1.
5 x - 7
3 × 4 + 1 = <em>13</em>
So, 5 x - 7 (x = 4)
= 5 × 4 - 7
= 20 - 7
= <em>13</em>
369
37 + 3 = 40
40 × 3 = 120
120 + 3 = 123
123 × 3 = 369
and so on
63.6 feet

2x-3x[x-1]
=2x-3x+1
=-x+1
=0
