Walkway over the hudson; a bridge that crosses the hudson river in poughkeepsie is 2.063 kilometers. anping bridge, which was built 850 years ago, is 2.07 kilometers long. which bridge is longer? how my longer?

For this case we have:

As both measurements are in kilometers, we can compare both numbers.

It is known that

Thus, the longest bridge is bridge 2.

To know the difference in length between the bridges, we subtract the quantities:

kilometers difference

The difference between the two bridges is 0.007 km

The longest bridge is bridge 2

The difference in length between the bridges of 0.007 km

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

hope to and hope that my answer is brainliest.(follow me )

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
