Approximately 1.7 miles per hour
The answer is 59,280 . To find you multiply 40 x 39 x 30 which 59,280
the answer is 45
because I know 15+15=30 and 30+15=45
so 45-15=30
hope it helps :)
A quadratic equation can be written as: ax² + b.x + c =0
But if you know the values of the 2 roots x' and x", you can write it:
a(x-x')(x-x"), Since the roots are given ( x' = -4 and x" = -5) and also a (=2)
then the equation becomes:
2(x + 4)(x +5) =0
Divide 2xz in each side
W/2xz=2xyz/2xz
W/2xz=y
