Step one know that across from 128 is 128 because of vertical angles
step two a straight line =180 so 128 -180 = 52
step three know you know 3k+4=52 so subtract 4 from 52 and that gives you 48 then divide by 3 to find k and 48/3 is 16
so k +16
because 16x3 is 48 then add 4 which is 52 and 52 plus 128 is 180
2 hours has more the the other so I would say it would be 8
To make a positive profit p(x)>0 we need to make:

Now we solve this for x:

We have:
a = -2
b = 7
c = -3
We will use formula for quadratic equation:

We got two solutions. One is fraction other is whole number. We will not consider fraction because the amount of muffins sold must be whole number. So our solution is:
x>3
Answer:
Irrational.
Step-by-step explanation:
The square root of 35 is not a perfect integer.
Answer:
Area = 31.5 units^2
Step-by-step explanation:
7 x 3 = 21
Area of triangle is (height x base) / 2
(3 x 7) / 2 = 10.5
21 + 10.5 = 31.5
