Q2. Axel and Lethna are driving along a motorway, They see a road sign. The road sign shows the due to Junction 8. It also shows the average time
drivers will take to get to Junction 8
To Junction 8
30 miles
26 minutes
The speed limit on the motorway is 70 mph.
Lethna says, 'We will have to drive faster than the speed limit to go 30 miles in 26 minutes.'
Is Lethna right?
You must show how you got your answer.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

central angle of a triangle has the same measure as its intercepted arc.

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
