x + (x + 3) + 
= 75
so you will add up all of the x 's but NOT the x^2
2x + 3 + = 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0
.66 is 66 out of 100. "out of" means divide
66/100
We can reduce this by dividing each number by the same amount - 2
33/50
Change 4.2 kilometers to meters, which is 4200 meters, then add that to 325, so 4525 :)
D. All of the above
is the correct answer.
I hope you like this answer and have a good night and life! :D
