Answer:
25x ²−49y ²
Step-by-step explanation:
We need to find product of (5x+7)(5x−7y)
By using identity (a+b)(a−b)=a −b ²
We have a=5x,b=7y
Thus (5x+7y)(5x−7y)=(5x) ²−(7y)

Answer:
2028 ft
Step-by-step explanation:
Let the feets of boards sold to get profit be x hence with the price of $1.13 which is inclusive of profit, the total sales will be 1.13 x
The cost per day will equally be the sum of variable cost which considers the feets of boards and the daily fixed charge. Considering the variable of $0.03 and fixed charge of $2230.80 then the equation is represented as 0.03x+2230.80
Relating the two equations then
1.13x=0.03x+2230.80 and rearranging like terms
1.13x-0.03x=2230.80
1.1x=2230.8
X=2230.8/1.1=2,028 ft
Therefore, to maximize daily profit, 2028 ft must be sold
Answer:
approx. 113.1
Step-by-step explanation:
Area formula: A= pi* (r^2)
12/2 = 6, so r=6
A= pi * (6^2)
A= pi * (36)
A = approx. 113.1
Second option is your answer order from least to greatest
answer: 50/8, 6 2/5, 6.45, 26/4
50/8 = 6.25
6 2/5 = 6.4
26/4 = 6.5
