Answer:
48
Step-by-step explanation:
i counted 24 2's and 24 x 2 is 48 also i did the math
Step-by-step explanation:
(2x-y+3)(2x-y-3)=
4x²-2xy-6x-2xy+y²+3y+6x-3y-9=
4x²-4xy+y²-9=
(2x-y)²-9
2(4z-3-21)=166-46
Combine like terms
2(4z-24)= 120
Distribute
8z-48= 120
Add 48 to both sides
8z= 168
Divide both sides by 8
z=21
Final answer: z=21
