To find this answer, all you have to do is reverse it. To start off, 32.5x = 78.65, from the problem. Then, all we do is solve for x by dividing both sides of the equation by 32.5, yielding x = 2.42.
I hope this helps, and mark brainliest if you want! :)
Have a good day!
Answer:
(a+4)(a-4)=a²-4² ITS LIKE THIS BECAUSE ITS AN IDENTITY,
⇒a²-16
Even when we solve it by the regular method of solving polynomials we get a²-16 as answer as there and thats the proof for the identity.
(a+b)(a-b)=a(a-4)+4(a-4)
⇒a²-4a+4a-16
⇒a²-16[NOTE:-4a+4a=0]
Thus we can see that a²-16 is the answer we get when we try to solve it by regular polynomial solution tooo.
And a²-16 is the polynomial from which we get (a+4)(a-4)
I found the table that accompanies this problem:
Time(h) 1 2 3 4 5
Distance (mi) 55 110 165 220 275
speed = distance / time
speed = 55/1 = 55 miles per hour
speed = 110/2 = 55 miles per hour
speed = 165/3 = 55 miles per hour
speed = 220/4 = 55 miles per hour
speed = 275/5 = 55 miles per hour
distance = speed * time
distance = 55 miles per hour * 6 hours
distance = 330 miles.
To get the distance traveled, simply multiply the speed by the number of hours spent travelling.
Answer:
36
Step-by-step explanation:
k(-3) = 2(-3)² - 5(-3) + 3
= 18 - (-15) + 3
= 33 + 3
= 36
