25x^2 - 16 = (5x - 4)(5x + 4)
OK. Then let's solve for ' r '. That means you have to come up with an equation that says r = everything else.
Step #1:
Write the equation you're given: <span>S = L (1 - r)
Let's divide each side by ' L ': S/L = 1 - r
Subtract 1 from each side : S/L - 1 = -r
Multiply each side by -1 : <em> 1 - S/L = r</em>
and there you have it.

0.96 yards of cloth was needed to make 2 bags.
Step-by-step explanation:
Let,
x be the yards of cloth used for each bag
y be the yards of cloth used of each apron
According to given statement
4x+5y=8.22 Eqn 1
5x+4y=7.44 Eqn 2
Multiplying Eqn 1 by 5
Multiplying Eqn 2 by 4
Subtracting Eqn 4 from Eqn 3
Dividing both sides by 9
Putting y=1.26 in Eqn 1
Dividing both sides by 4
Cloth required for one bag = 0.48 yards
Cloth required for 2 bags = 0.48*2 = 0.96 yards
0.96 yards of cloth was needed to make 2 bags.
