The answer is 25 . if x=5 , then you have 5^2, which is 25
Answer:
Ravi had 355ml water to begin with.
Step-by-step explanation:
Given that,
amount of water that Gwent pour in Ravi = 256 ml
amount of water that Henry pour in Ravi = 189 ml
amount of water after each have poured = 800 ml
suppose amount of water ravi had before both poured water in it = x
Equation
256 + 189 + x = 800
445 + x = 800
x = 355ml
Initially ravi had 335ml of water.
F(-4) = 3 x 2 - 5(-4) + 4
3x2= 6
-5(-4)= 20
6-20= -14
-14+4= -10
f(-4) = -10
I think the answer is 381
