Answer:
(2x-3)(2x+3)
Step-by-step explanation:
4x^2-0x-9
(4x^2-9)
(2x)^2 - (3)^2
We recognize that this is the difference of squares a^2 - b^2 = (a-b)(a+b)
(2x-3)(2x+3)
Answer:
number of trousers=14
numbers of pairs of stockings=71
Step-by-step explanation:
Pairs of stockings: x
T shirt: y
Trouseres: z
7x=3y
1z=1y+2×
__________________________________________
m: number of trousers
m*z=26y
m*(y+2x)=26y
m*(y+2(3y/7))=26y
m=26y/(y+2(3y/7))
m=14
You need to buy 14 trousers that represents the equivalent of 26 T-shirts.
__________________________________________
k:pairs of stockings
k*x=10y+11z
k*x=10(7x/3)+11(y+2x)
k*x=10(7x/3)+11((7x/3)+2x)
k=71
You need to buy 71 pairs of stockings with an amount equal to the price of 10 T-shirts and 11 trousers
