I guess A i don't know hope the answer is correct
a. 3h = -12 + 5s
b. Speed = 51. 6 miles per hour
c. Height = 76 feet
<h3>How to determine the value</h3>
Given the function;
5s - 3h = 12
Where;
- s is the speed in miles per hour
- h is the height in feet
a. To solve for 3h
We have;
- 3h = 12 - 5s
3h = -12 + 5s
b. If the height is 82 feet , then
5s - 3(82) = 12
5s - 246 = 12
collect like terms
5s = 12 + 246
5s = 258
Make 's' the subject
s = 258/ 5
s = 51. 6 miles per hour
c. If the speed is 48 miles per hour, we have;
5(48) - 3h = 12
240 - 3h = 12
collect like terms
-3h = 12 - 240
-3h = -228
Make 'h' the subject
h = -228/ -3
h = 76 feet
Thus, the speed and height are 51. 6 miles per hour and 76 feet respectively.

Answer:
Answer is D hope this helps :)
Step-by-step explanation:
a. Factorize the denominator:
Then we're looking for 
such that
If 
, then 
; if 
, then 
. So we have
as required.
b. Same setup as in (a):
We want to find 
such that
Quick aside: for the second term, since the denominator has degree 2, we should be looking for another constant 
such that the numerator of the second term is 
. We always want the polynomial in the numerator to have degree 1 less than the degree of the denominator. But we would end up determining 
anyway.
If 
, then 
; if 
, then 
. Expanding everything on the right then gives
which tells us 
and 
; in both cases, we get 
. Then
as required.
