Answer:
76
Step-by-step explanation:
4^2 x 5^2 - 18^2
PEMDAS is our acronym for order of operations: Parentheses, exponents, multiplication, division, addition, subtraction.
Since we have no parentheses, we'll calculate the numbers and exponents (PEMDAS) first. "to the power of 2" is also called "squared" and means multiplying that number by itself.
(4x4) x (5x5) - (18x 18)
=16 x 25 - 324
Now we multiply: (PEMDAS)
= 400 - 324
then subtract: (PEMDAS)
=76

The equation 
has two variables, y (longevity of car engine) and x (number of times oil changed).
This falls into the slope-intercept form of a linear function,which is 
, where b is the y-intercept (or in other words, the value of y when x is 0).
Comparing our equation to the slope-intercept form of a linear function tells us that the value 0.1576 is the y-intercept.
<em>It means </em><em>0.1576</em><em> is the expected longevity of a car engine when x is 0 (number of oil changed is 0). </em>This is answer choice A.

Hi there!
Question 6)
The scale is 1 cm : 18km.
This means that for every 1 cm, there is 18 km
So, we are going to set it up like a proportion:
cm 1 9
km 18 x
Now we are going to cross multiple:
1*x=9*18
Solve for x:
x=152
Therefore, the answer is 152 km
question 8)
Yet again we have a proportion problem.
15 10
18 x
15x=180
x=12ft
Therefore, the answer is 12 feet.
Question 10)
This question is just like the other one!
3. 6
7. x
3x=42
x=14
Therefore, the answer is 14 feet
