Answer:
the coefficient of x is 1
Step-by-step explanation:
In the expression ax²+bx+c=0
a is the coefficient of x²
b is the coefficient of x
2+x²+x = x²+x +2 = 1x²+1x +2 =
So in this expression right above the coefficient of x is 1
(6k+2)-(3k-2)
expand brackets 18k²-12k+6k-4
simplify 18k²-6k-4
So for this you need to find 15% of 60. There are a few ways to do this but I prefer to do it like this.
First, find 10% of 60. This can be found by dividing 60 by 10, because 100%/10% is 10.
This gives 10%=6
5% is half of 10%, so divide your answer for 10% (6), by 2.
This gives 5%=3
We needed 15%, so we add our 10% and 5% together, to get 9.
15% of 60 is 9, meaning there are 9 puppies.
Hope this helps!
