Answer:
<em>The app's estimate was 38.4 minutes.</em>
Step-by-step explanation:
Suppose, the app's estimated time was 
minutes.
Given that, it took 48 minutes to drive downtown. So, <u>the error in estimated time by the app</u> 
minutes.
It is also given that the error was 20%. So, <u>the amount of error</u> 
minutes.
Thus, the equation will be......
So, the app's estimate was 38.4 minutes.
<span>x2 − 7x + 18
is prime
there is no way you can make two numbers multiply to get positive 18 and add to get negative 7
</span><span>(x − 9)(x − 2) = x^2 - 11x + 18
(x − 9)(x + 2) = x^2 -7x - 18
(x + 9)(x + 2) = x^2 +11x + 18</span>
Im assuming it would be 60 or 60.375(Work below)
Because usually when it says "out of" it means divide so i divided 8 from 21 and got 2.625 so then i took the 63 and subtracted 2.625 from that and got 60.375 so its either 60 or 60.375 again im not sure if im wrong im very sorry.
Ok
Lets start:
is 36
then you add 8 which would be 44.
then do 7 times 2 which is 14, then add 11, which is 25.
is 44 divided by 25, which would be 1.76
