Sure, I'm bored anyways XD
Step-by-step explanation:
Find the velocity of the car
v = d/t
v = 192.5/3.5
v = 55 miles/hour
Find the time to travel 495 miles
t = d/v
t = 495/55
t = 9
It will take 9 hours to travel 495 miles
A) (32x² + 24x +12) / 16. Notice that the GCD of 32, 24 and 12 is 4
then let's factorize:
4(8x² + 6x + 3) / 16. Now simplify numerator & denominator by 4
Hence a) = (8x² + 6x + 3) / 4
b) 35/(42x² - 49x +21); the GCD (of denominator) of 42, 49 and 21 is 7
then let's factorize:
35/[7(6x² -7x +3); Notice that 35 = 7.5 ; 7.5/ 7(6x²-7x+3)
Now simplify numerator & denominator by 7
Hence b)= 5/(6x²-7x+3)
Now do the same for the others.
Answer:
$67.28
Step-by-step explanation:
First you distribute. 4 to x-1 and 3 times 2x-5 you should get 4x-4-6x+15 because -3 times -5 is positive 15. Combine like terms 6x-4x is 2x and 15-4 is 11
