Answer:
x²^2 + 4x + 4 - 9y²=(x+2-3y) (x+2-3y)
Step-by-step explanation:
hello :
x²+4x+4 = x²+2(2x)+2²=(x+2)² use identity : (a+b)² = a²+2ab+b²
( x² + 4x + 4) - 9y² = (x+2)²-(3y)² = (x+2-3y) (x+2-3y) use identity :
a²-b² =(a-b)(a+b)
1 mL is equal to 1 cm3 and so 1 x 3=3, which is why the answer is 3 cm3.
3 cm3
If both machines are working at once, 200 tshirts (100 in each machine) could be made in 100 minutes, if 200 shirts can be made in machine 1 in 50 minutes, it will take 25 minutes to make 100. machine b takes 150 minutes per each 200, 150 divided by two is 75. 75 + 25 = 100 minutes
It would work better just to use machine one and take 50
minutes, but i dont think thats an answer choice.
edit: i think from the choices your answer would be: 37.5 as if both machines run at once more tshirts can be made
I'm 87% sure the answer is B
