The permutation and the combination would be ^{15}P_4= 32760 and ^{15}C_4 = 1365.
<h3>What is the formula used for permutation and combination?</h3>
To calculate permutation
Given; n = 15, k = r = 4
Therefore, ^{15}P_4 = 32760

We let C be the cost
x be the number of loaves
cost = overhead cost+ cost to bake - selling price
cost = 90 + 0.60x - 1.50x
cost = 90 - 0.90x

Answer:
w = ( x - 10)
Step-by-step explanation:
area of the garden = x² - 25x + 150.
factorise the expression to find the x values.
x² - 25x + 150 = (x - 15)( x - 10) -15-10 = -25
-15*-10= 150
as the garden is rectangle, it's area will be = lw.
a = l × w
a = (x - 15)( x - 10)
one among them is the width, the other the length. if the length is (x - 15), then reasonably the width will be (x - 10).
hope this helps you, au revoir!
