So let's find the unit rate of these.
18 mi/ 2 hrs = 9 mi/ 1hr
45 mi / 5 hrs = 9 mi/ 1 hr
So you are running 9 miles an hour.

The answer to 20+50 is 72
No because 26 isn’t in the multiples of three
Complementary angles are angles that measure up to 90 degrees.
To find the measures of the two angles, divide 90 by two to say two angles of 45 degrees. Now divide 14 by 2, which you get 7 with. Now add 7 to 45 and subtract it from 45 as well, to get 52 and 38.
The measures of the angles are 52 degrees and 38 degrees.
49w² -112w + 64
first, you have to find 2 numbers that add up to equal -112, but also multiply together to get a product of 3136 (49 * 64)
two numbers that add to -112 and multiply to equal 3136 is -56 and -56
we can add them into the equation by putting them in for -112x
49w²-56w-56w+64
we now look at what the first 2 numbers have in common and what the last two numbers have in common
49w² and -56w both have w and 7 in common so we can divide 7w
7w(7w -8)
-56w and 64 both have -8 in common so we can divide by -8
-8(7w-8)
now we take the 2 numbers on the outside and bring down the numbers in the brackets
(7w-8)(7w-8)
(7w-8)²
