<span>2 square root (x - 5) = 2. 2^2 (x -5) = 2^2. 4(x - 5) = 4. 4x - 20 = 4. 4x = 24. x = 6. This solution is not extraneous, because extraneous solutions emerge from solving the problem but are not actually valid solutions for the initial problem. With rounding, this solution is valid for the initial problem.</span>
Answer:
-0.5 is the answer I think
Rice: .5(8) = 4kg (4000 g)
Popcorn: 150(12) = 1800 g
Total mass = mass of rice (4000 g) + mass of popcorn (1800g)
So...
Total mass = 5,800 g (or 5.8 kg)
Step-by-step explanation:
is the number of unit squares that cover surface of a figure.
F(3k)=3k +7 Equals 9k+7. So 9k+7 would be the Answer.
