simplify 4 square root of 2 end root plus 7 square root of 2 end root minus 3 square root of 2. 2 square root of 8 8 square root
Alex787 [66]

<u>Answer</u>

8√2


<u>Explanation</u>

Simply: 4√2 + 7√2 - 3√2

Let √2 = x

4√2 + 7√2 - 3√2 = 4x + 7x - 3x

                             = 11x - 3x

                             = 8x

Substituting x with √2

4√2 + 7√2 - 3√2 = 8√2

A toxic radioactive substance with the density of 4 mg/cm² is detected in the been detected in the ventilating ducts that was us
Kruka [31]
The formula for half-life is:

A = P(0.5)^{t/h}

A is the amount remaining, P is the initial amount, t is the time that has passed, and h is the half-life of the substance.  Plug in the values that you know and solve:

4 = P(0.5)^{35/20} \\ \\ 4 = P(0.5)^{1.75} \\ \\ P = \frac{4}{0.5^{1.75}} \\ \\ P \approx 13.4543426441

Rounded to the nearest whole number, the density of the substance was about 13<span>mg / cm².</span>
