Answer:
x = 4 and -10
Step-by-step explanation:
Given the equation
x²+6x-40= 0
The common factors to use for the factorisation are +10 and -4
x²+(10x-4x)-40=0
(x²+10x)-(4x-40) = 0
x(x+10)-4(x+10) = 0
(x-4)(x+10) = 0
x-4 =0 and x+10 = 0
x = 4 and x = -10
Okay. So 7:30-10:00 is 2 hours 30 minutes or 2 1/2 hours. To find this, we have to do 156/60 to find the amount of time it takes to get there. 156/60 is 2.6, so it would take more than 2 1/2 hours to arrive in London. Kim does not arrive in London before 10:00 AM.
