Step-by-step explanation: idk how to solve the other two
X^2+10x+25= 24+25
(x+5)^2= 49
x+5= +-7 (plus or minus 7)
x= -7-5
x=-12
x=7-5
x=2
Final answer: x={-12, 2}
Answer: 82.3 g
Step-by-step explanation:Moles Cu = 300 g x 1 mol Cu/63.55 g = 4.72 moles Cu
Moles Zn = 4/15(4.72) = 1.26 moles
mass Zn = 1.26 moles x 65.38 g/mol =
