Simplified expression for 8(x-6)-4 (x-5) 5x?
I'll do it step by step so you actually understand it: 8(x-6)-4 (x-5) 5x - Distribute 8x -48 -4x +20 5x - Combine like terms Is the 5x multiplied by the (x-5) or is it a separate term like +5? If it's multiplied: 8x-48-4x+100x 104x - 48 - Final answer If it's a separate term: 8x-48-4x+5x 9x - 48 - Final Answer David forgot a term.
Simplify the expression?
1) (14 + x + 5) / (3x) = (19+x)/(3x) 2) 1/(x+2) 3) 6/2x + 2/2x = 8/2x = 4/x 4) 4/5x - 15/5x = -11/5x Do you mean x^2 for 3) ? If so, then the correct answer is: (3/x)^2 + 2/x^2 = 9/x^2 + 2/x^2 = 11/x^2
It's already in simplest form.Maybe
First, let’s simplify [math](5x)^{5/2}[/math]. By the laws of exponents, we can write that as [math]5^{5/2} \cdot x^{5/2}[/math]. Now, we multiply it my [math]x^{-4/5}[/math] from the problem. Using the laws of exponents, we can add the powers if the base is the same, so we write the top of the fraction as [math]5^{5/2} \cdot x^{5/2 - 4/5}=5^{2.5} \cdot x^{1.7}[/math]Because square root is the same as raising to the 1/2 power, we apply the laws of exponents on the bottom: [math]\sqrt{5x^3} = 5^{0.5} \cdot x^{1.5}[/math]We know that dividing exponents with the same base is the equal to subtracting their exponents, so our final answer is [math]5^{2.5–0.5} \cdot x^{1.7 - 1.5} = 5^2 \cdot x^{1/5} = 25x^{1/5}.[/math]

Simplify expression:(2x)(5x)-23 when X=4?
(2*4) * (5*4) - 23 = 137 -2y-6 +6y +6 = 4y (5x)(14)-20 = 70x-20 Since you're just simplifying, not solving equal to 0, that's as simple as you can get it. Obviously you should try to do these on your own, this is basic stuff you need to learn since it is going to build from here.....but for everyone just telling you you're dumb, that's not what yahoo! answers are for. Maybe he needs help and wants to double check his answers before a test? Not up to you to solve his life, just answer his questions.
Simplifying Expressions?
Elizabeth simplified it wrong.... So... first 5x-3 (4-x), multiply -3 by 4 and -x This will be, 5x-12+3x Then, simplify.... 5x+3x=8x. So, 8x-12 Simplify that, (pull out common factor 4. So the answer is 4 (2x-3) Number 2... No.. they are not equivalent. You can see it already. Lets do first side first... 5x+3x-5x.... 5x-5x=0 so w hats left is 3x. Lets do next side of the equation... 7xy-4y cannot be simplified... unless u are factoring (by pulling out a y. BUT ANYWAYS.... WHATEVER WAY YOU DO IT... THEY ARE NOT EQUAL! HOPE I HELPED!!!!!!XD
Because the following question also has to deal with functions in that the square root graph must be represented as a function, the proper answer for the sqrrt(4x^2) would be 2|x| because functions can never have repeated x values. The moet basic way to check this on a graph is through a “vertical line test” where if you are to put a vertical line (a linear graph with a slope of undefined) anywhere on the graph, and you find more than one point on one x value, the graph is not considered a function. The square root graph would not have been a function if it was an inverse graph of the quadratic graph without a restricted domain. But because there is a restricted domain of x>= 0, the principal square root graph is a function located only in Quadrant I if no transformations are performed on it. Because it is in Quadrant I, both the y-values and the x-values must be positive and therefore -2x is not a possible outcome or at least considered a rational outcome of the square root of 4x^2 while 2|x| is the only possible outcome because the value will surely be positive because of a positive 2 multiplying by a positive x because the absolute value around it makes it positive.
Simplify the rational expression x^2 + 5x + 4 /x^2 + 7x + 6?
Since no one knows how to explain anything and just give the answer with no context, I'll explain: (x² + 5x + 4) / (x² + 7x + 6) The first step here is to factor what we can: (x + 4)(x + 1) / [(x + 6)(x + 1)] So at this time, we can see that x cannot equal -1 or -6 otherwise you will have a denominator of 0. You have a common set of factors of (x + 1) that can be cancelled out. That leaves: (x + 4) / (x + 6) Though the values of x still cannot be -1 or -6 otherwise the denominator of the original expression is zero. Hope this explanation helps. Best answer if it did.
