Which statement is true about this argument? premises: if two lines are parallel, then the lines do not intersect. lines m and n do not intersect. conclusion: lines m and n are parallel. which statement is true about the argument? the argument is not valid because the premises are not true. the argument is not valid because the conclusion does not follow from the premises. the argument is valid by the law of detachment. the argument is valid by the law of syllogism.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Can someone plz me understand how to do these. plz, show work. in exercises 1-4, rewrite the expression in rational exponent form.[tex]\sqrt[4]{625} \sqrt[3]{512} (\sqrt[5]{4} )³ (\sqrt[4]{15} )^{7}\\ (\sqrt[3]{27} )^{2}[/tex]
