Answer:
x = 3
y = 15
Step-by-step explanation:
If △XPS ≅△DNF, their corresponding sides would be congruent. This implies that:
XP ≅ DN
PS ≅ NF
XS ≅ DF
Given that:
XP = 4y - 3
DN = 57
NF = 51
XS = 17x + 3
DF = 54
Therefore:
XP = DN
4y - 3 = 57 (Substitution)
Add 3 to both sides
4y = 57 + 3
4y = 60
Divide both sides by 4
y = 60/4
y = 15
Also,
XS = DF
17x + 3 = 54 (substitution)
Subtract 3 from each side
17x = 54 - 3
17x = 51
Divide both sides by 17
x = 51/17
x = 3

Answer:
Final Temperature of the gas = 416K
Step-by-step explanation:
Using the Charles Law;
V₁/T₁ = V₂/T₂
V₁ = 0.61m³, V₂=3.9m³, T₁= 65K, T₂ = ?
T₂ = V₂T₁/V₁ = (3.9 x 65)/0.61 = 415.57377K ≅ 416K
