Let’s start with -4(-3x + 11) so, -4•-3x is 12x,because multiplying 2 negatives creates a positive. As for -4•11, it is -44. So, it should be 12x + -44. I hope this helps!
1.7 miles: subtract 1.5 from 3.2 which equals 1.7 (make sure to line up the decimals!)
For the first one it is 5 x10^{8}
and for the second one it is 0.0005 = 5 × 0.0001 = 5 × 10−4
2x+4-3/2x= 1/3(x+5
3x+1 it needs a lot of time
