Answer:
27x - 2
Step-by-step explanation:
First off, we use commutative property to get the like terms together.
(20x + 7x) - (3-5)
Now we can solve the equations inside the parenthesis.
27x - (-2)
Because these aren't like terms, this is as far as we can go. Meaning 27x - 2
is out answer.
Answer:
9.
Step-by-step explanation:
The highest power is 3*3 = 9, so it's 9.
The first thing we must do for this case is to define variables.
We have then:
x: number of slices
y: total cost
We write the linear function that relates the variables.
We have then:

Then, we evaluate the number of slices to find the total cost.
-two slices cost:
We substitute x = 2 in the given equation:

Answer:
two slices = 2.2 $
-ten slices cost:
We substitute x = 10 in the given equation:

Answer:
ten slices = 11 $
-half a slice cost:
We substitute x = 1/2 in the given equation:

Answer:
half a slice = 0.55 $
Answer:
-1.96312>-2.2360
Step-by-step explanation:
first find -
which is -2.2360679775
now round it to match the lenth of the other problem
-1.96312...
-2.2360...
now remember that the bigger the negitive number, the smaller it really is,
so
-1.96312>-2.2360
X² + 4x + 4 = (x+2)²
