Answer:
4x^2 + 21x - 18
Step-by-step explanation:
(9x^2+24x-8)-(5x^2+3x+10)
9x^2+24x-8-5x^2-3x-10
9x^2 - 5x^2 = 4x^2
24x - 3x = 21x
-8 - 10 = -18
Answer: 4x^2 + 21x - 18
Hello there!
Speed has the following formula:
S =
![\frac{D}{T}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7BD%7D%7BT%7D%20%20)
, or
Speed is equivalent to
Distance divided by Time.Let's check out our problems to solve for the speed.
16.)
We have 770 miles, which is a measure of distance.
We have 120 minutes, which is a measure of time.
Let's substitute our variables with these numbers.
S =
![\frac{770}{120}](https://tex.z-dn.net/?f=%20%5Cfrac%7B770%7D%7B120%7D%20)
Simplify.
S = ~6.41 Mi/min
17.)
We have 2.5 mi, which is our measurement of distance.
We have 0.5 h, which is our measurement of time.
S =
![\frac{2.5}{0.5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2.5%7D%7B0.5%7D%20)
Simplify.
S = 5 Mph (When you divide by 0.5 you are multiplying the numerator by 2).
18.)
We have 244 km, our distance.
We have 2.5 h, our time.
S =
![\frac{244}{2.5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B244%7D%7B2.5%7D%20)
Simplify.
S = 97.6 km/h
I hope this helps!
