Answer:
Step-by-step explanation:
speed = distance/time
so renaldo speed = 3.2/0.5 = 6.4miles/hr (since time taken is 1/2 hr)
now after 1 hr of his appoinment i.e at 5:30pm he took bus whose speed is same as before i.e 6.4 miles/hr
now time taken to cover this 4.8 miles = 4.8/6.4 = 3/4 hr (since time = distance /speed )
3/4 hr = 3/4 * 60 = 45 minutes
so he reached at 6:15pm . so he will be on time.
Ofcourse it is a linear function
why because every of x value of this function is 23 in result always
... so when we draw a chart it will be line on 23 coordinate ;)
A is the answer because x^2-6x-7 is (x-7)(x+1).

Answer:
D) It is doubled
Step-by-step explanation:
Regardless of the side length, if the area of a square is quadrupled, the side lengths get doubled, as shown in the diagram. If all of the side lengths are doubled, that means the perimeter is also doubled.
