Answer:
the number A(t) of grams of salt in the tank at a time is <em>A(t)=150-110e-t/50</em>
<h2>♪Answer :</h2>
»(4x - 2y)(3x + 5y)
»4x(3x + 5y) + (-2y)(3x + 5y)
»12x² + 15xy - 6xy - 10y²
»12x² + 9xy - 10y²
so, ABC is :

A function assigns the values. The sum of the two function will be equal to 3[√(x-3) + 5].
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given f(x)=√(x-3) and g(x)=[√(4x-12)]+15, therefore, the sum of the two function will be written as,

![= \sqrt{x-3} + \sqrt{4(x-3)}+3(5)\\\\ = \sqrt{x-3} + 2\sqrt{(x-3)}+3(5)\\\\= 3\sqrt{(x-3)}+3(5)\\\\ = 3[\sqrt{(x-3)}+5]](https://tex.z-dn.net/?f=%3D%20%5Csqrt%7Bx-3%7D%20%2B%20%5Csqrt%7B4%28x-3%29%7D%2B3%285%29%5C%5C%5C%5C%20%3D%20%5Csqrt%7Bx-3%7D%20%2B%202%5Csqrt%7B%28x-3%29%7D%2B3%285%29%5C%5C%5C%5C%3D%203%5Csqrt%7B%28x-3%29%7D%2B3%285%29%5C%5C%5C%5C%20%3D%203%5B%5Csqrt%7B%28x-3%29%7D%2B5%5D)
Hence, the sum of the two function will be equal to 3[√(x-3) + 5].
