Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.
Say you have an algebraic expression y = 3x +4 For a given value of x = 5 substitute that number in place of x in the expression, so in this case y = 3(5) + 4 = 19
It is: (-4*-2)3 = 512
To multiply a sum by a number,multiply each addend of the sum by the number outside the parentheses.For any numbers a, b, and c, a(b+c) = ab + ac and a(b-c) = ab - ac.Example: 2(5-3)= (2 times* 5) - (2 times* 3). Times*_multiply

Assume that the expression 4x5 in the question is 4x5.4x5 = 3 : x5 = 3/4 : x = 5√(3/4) : then 2k.5√(3/4) + 10 = 2 : 2k.5√(3/4) = 2 - 10 = -8 :k = -4 ÷ 5√(3/4) = -4 ÷ 0.9441 = -4.2369 (4dp)
This expression is an example of the Distributive Property. The expression a(b+c) = ab +ac is true because of the Distributive Property.

The value is 1 if (x, y) = (4, 3) and 0 otherwise.
If you mean: 3+4+6+2*(58) then it is 129

If you mean: 9x squared-12x+4 when x = 3 Then it is: (9*3*3)-(12*3)+4 = 49
