|-15| = 15
|25| = 25
|-40| = 40
|10| = 10
The absolute value of a negative or positive number will always be positive.
c. -40 will have the greatest absolute value.
Your final answer is c. -40.
A. A coefficient is a constant multiplied with a variable. Example is 20 for 20c and 35 for 35w. A variable is expressed in numerical letters like cfor 20c and w for 35w. A constant is merely a number, like 23.50.
b. w = 12, c = 3; substitute these values to the given equation :
20c+35w+23.5 = ?
20(3)+35(12)+23.5 = $503.5
c. The expression would change for the term 20c. Instead of 20c,it would then be changed to 25c. Note that the equation was made from the problem statement. If one statement changes, then the mathematical terms would be affected. The rest of the other terms would remain as is.

Answer:
Step-by-step explanation:
Second option correct
Given two numbers x and y such that:
x + y = 12 ... (1)
<span>two numbers will maximize the product g</span>
from equation (1)
y = 12 - x
Using this value of y, we represent xy as
xy = f(x)= x(12 - x)
f(x) = 12x - x^2
Differentiating the above function:
f'(x) = 12 - 2x
Maximum value of f(x) occurs at point for which f'(x) = 0.
Equating f'(x) to 0 we get:
12 - 2x = 0
2x = 12
> x = 12/2 = 6
Substituting this value of x in equation (2):
y = 12 - 6 = 6
Therefore, value of xy is maximum when:
x = 6 and y = 6
The maximum value of xy = 6*6 = 36
