$58-$25=x this would be the equation i believe

Answer: 14x - 8</h3>
=======================================================
Explanation:
I'll use the quadratic formula to find the roots or x intercepts. This slight detour allows us to factor without having to use guess-and-check methods.
The equation is of the form ax^2+bx+c = 0
This leads to...
Now use those roots to form these steps
Refer to the zero product property for more info.
Therefore, the original expression factors fully to (4x-5)(3x+1)
Use the FOIL rule to expand it out and you should get 12x^2-11x-5 again.
----------------------------------------------
We did that factoring so we could find the side lengths of the rectangle.
I'm using the fact that area = length*width
- L = length = 4x-5
- W = width = 3x+1
The order of length and width doesn't matter.
From here, we can then compute the perimeter of the rectangle
P = 2(L+W)
P = 2(4x-5+3x+1)
P = 2(7x-4)
P = 14x - 8
Answer: m=3/2
Step-by-step explanation: the slope starts from the left side and the line is going up meaning its positive, now the line is going up by 3s and to the right in 2s.
Answer:
question no 1:slope=5
Step-by-step explanation:
let(x=5andy=8)(a=7andb=18)
now
slope=(b-y)/(a-x)=(18-8)/(7-5)=5
Answer:
For the cost from the two methods to be equal, 3,200 books have to be produced
Step-by-step explanation:
In this question, we are asked to calculate the number of books that will be produced for two methods of production having different fixed and variable costs to have the same production cost.
Since the number of books is something we do not know, let’s represent it with a variable called c.
For the first production method, the cost of production will be ; 58,881 + 8.50c
For the second production method, the cost of production will be; 18,081 + 21.25c
Now since they are said to be equal, we proceed to equate both;
58,881 + 8.5c = 18,081 + 21.25c
58,881-18,081 = 21.25c - 8.5c
40,800 = 12.75c
c = 40,800/12.75
c = 3,200 books
