Step-by-step explanation: -3x^4+4-8 > =-3x^4-4

The Area of Shaded region is equal to the difference in Area of rectangle and Area of triangle .
let's solve for area of rectangle :



Now, Area of Triangle :



So, the area of the shaded region in terms of x :


And since, Area of Shaded region = 44 cm²
By equating the area, we get

Value of x = 2

Answer:
<h2>d. $250</h2>
Step-by-step explanation:
We can use the equation of a straight line to model the cost of servicing the car.
let the cost be y and the number of hours be x
and the charge per hour is m
y=mx+c
y=50x+25
given that the time is 3.45 hours it is assumed that the charge is for 4 hours since for a fraction of 0.45 hours we are charged $50
y=50(4)+25
y=200+25
y=$225
