To find the zeroes you make the function equal to zero and then solve.

Then factor out the x to get a quadratic inside the parentheses.

Factor the inside quadratic formula.

Lastly, use the zero product property to solve.

We know that 7/10 of the cookies are chocolate chip, so that means there are 3/10 of the cookies left.
We now want to find what 3/4 of 3/10 is.
We can do this by multiplying both fractions
3/4x3/10 (we just multiply across) to get 9/40.
We cannot simplify this answer, so our final answer is 9/40 of the cookies are sugar cookies.
Answer:

Step-by-step explanation:
to find the perimeter of a shape you add all of the side lengths together
20+20+20+20
Step-by-step explanation:
5(2h+8) <60
10h +40< 60
10h + 40-40 < 60-40
10h < 20
10h/10 < 20/10
h < 2
