Answer:
45 mph
Step-by-step explanation:
It took the car 4 hours to travel 180 miles
Then
It took the car 4/4 hours to travel 180/4 miles
Since 4/4 = 1 and 180/4 = 45
It took the car 1 hours to travel 45 miles
Therefore ,the car was it going at 45 mph
A. (4x + 9) (4x − 9) is the correct answer.

Hello,
I suppose you mean f(x)=3^x /2
g(x)=3^(-x) /2
20% of $1200 is $240
(0.2∗1200)=$240
Now subtract that number from 1200
1200−240=$960
try this example
For a given rectangle,the area(A) is the product of its length and width
A=lw, given A=350m² and l=50m
transposing the equation for w gives w=A/l
w=350m²/50m=7m
That's it
