Answer:
8y3 +6y2- 29y +15
Step-by-step explanation:
(4y − 3)(2y2 + 3y − 5)
8y3 + 12y2 -20y -6y2 -9y +15
8y3 +6y2- 29y +15
Given that a vehicle travels 25 miles in 2 hours, determine the average speed of the vehicle in miles per hour.
Work:
In order to find the average mph of the vehicle, you have to divide the distance the vehicle travels in a certain period of time by that amount of time.
So, in this case, the vehicle traveled 25 miles in 2 hours, so you would divide 25 by 2.
25/2 = 12.5
That means, the vehicle is traveling at a speed of 12.5 mph.
Thus, the average speed of the vehicle is 12.5 miles per hour (mph).
Answer:
The probability of drawing a red marble = 2/5. The probability of drawing a blue marble is now = 1/4.
Step-by-step explanation:
answer:
52
step-by-step explanation:
- we can use the 45-45-90 triangle theorem for this: x, x, x
this is because this is a square
- squares have two sides of the same length, and the diagonal is different
- the x's stand for the sides, whereas the x stands for the diagonal
x = 26
x = 13
- now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4
13 X 4 = 52
