The left hand side expression of the given equation is a difference of two squares. The first term, x², is a square of x and the second term, 25 is the square of 5. The factors of the expression are (x - 5) and (x + 5).
(x - 5)(x + 5) = 0
The values of x from the equation above are x = -5 and x = 5.
We know that
3 3/8-------------> (3*8+3)/8-----------> 27/8 yd
if 1 dress take---------------> 27/8 yd
X-----------------------------> 3375 yd
X=3375/(27/8)---------> x=1000 dresses
the answer is
He can make 1000 dresses

Answer:
7 1/8
Step-by-step explanation:
Convert the mixed fractions to normal fractions:
(9 * 4) + 2 = 38
(1 * 3) + 1 = 4
38/4 ÷ 4/3
Reduce it down as much as possible:
19/4 ÷ 4/3
Apply the fractions formula for division:
a / b ÷ c / d = a * d / b * c
19 * 3 / 2 * 4
57 / 8
Simplify:
7 1/8
