Richard walks
1 kilometer : 10 minutes
That would mean
6 kilometers : 60 minutes
<span>Hope that helps and correct me if I'm wrong!</span>
She will need to drive 110 miles to be the same
21 I think I'm not sure tho
It will take him 240 min and if u convert that it will take him 4 hours
We know that
x²+px−35=0-------> <span>has one root that is equal to 7
so
substitute x=7 in the equation
</span>7²+p*7−35=0
49+p*7−35=0
14+p*7=0
p=-14/7------> p=-2
the answer Part a) is
t<span>he value of the coefficient p is -2
</span>
Part b) <span>Find the other root
</span>x²+px−35=0-----> x²-2x−35=0
<span>
using a graph tool-------> to resolve the second order equation
see the attached figure
the other root is
x=-5
the answer part b) is</span>
the value of the other root is -5<span>
