Answer:
The quantity of first nut = x = 2.4 lb
The quantity of second nut = 12.9 - x = 12.9 - 2.4 = 10.5 lb
Step-by-step explanation:
Let amount of first type of nut = x
Amount of second type of nut = 12.9 - x
Total Cost of first type of nut = 4.5 x
Total Cost of second type of nut = 8.8 × (12.9 - x)
Total cost of both type of nut = 8 × 12.9
Total cost = Cost of first type of nut + Cost of second type of nut
8 × 12.9 = 4.5 x + 8.8 × (12.9 - x)
103.2 = 4.5 x + 113.52 - 8.8 x
8.8 x - 4.5 x = 10.32
4.3 x = 10.32
x = 2.4
Therefore the quantity of first nut = x = 2.4 lb
The quantity of second nut = 12.9 - x = 12.9 - 2.4 = 10.5 lb

Answer:
feet
Step-by-step explanation:
Total length of the board = 
feet
Length of board that is removed from the larger board = 
When a smaller board is removed, the length of the remaining board can be calculated using subtraction as:
Remaining Length of board = Total Length - Length of smaller board
= 
This means feet of board remains after removing the smaller board from it.

Answer:</h2>
The value of x is -1/2
<h2>
Step-by-step explanation:</h2><h3>Question :</h3>
Solve the equation of f(x + 2) = f(x - 2) + 4, where f(x) = 3 + 2x + x^2
<h3>Solution :</h3>
First, we need to split the equation and find the answer to each function
f(x + 2) = 3 + 2(x + 2) + (x + 2)^2
f(x + 2) = 3 + 2x + 4 + x^2 + 4x + 4
<u>f(x + 2) = x^2 + 6x + 11</u>
f(x - 2) = 3 + 2(x - 2) + (x - 2)^2
f(x - 2) = 3 + 2x - 4 + x^2 - 4x + 4
<u>f(x - 2) = x^2 - 2x + 3</u>
Second, we need to find the value of x
f(x + 2) = f(x - 2) + 4
=> x^2 + 6x + 11 = x^2 - 2x + 3 + 4
=> x^2 - x^2 + 6x + 11 = - 2x + 3 + 4
=> 6x + 11 = -2x + 7
=> 6x = -2x - 4
=> 6x + 2x = -4
=> 8x = -4
=> x = -1/2
<h3>Conclusion :</h3>
The value of x is -1/2
