Answer 1

$\mathbf{R(x)-S(x)}\\\\37x^2-7x+15-(23x^2+19x-24)\\\\37x^2-7x+15-23x^2-19x+24\\\\14x^2-26x+39\\\\\boxed{\mathbf{A)-26}}$

$\mathbf{M(x)+N(x)}\\\\36x^5+24x^3+5x+3+(-25x^5+5x^3-2x)\\\\36x^5+24x^3+5x+3-25x^5+5x^3-2x\\\\11x^5+29x^3+3x+3\\\\\boxed{\mathbf{D)11}}$

$\textbf{Efect\'ua en cada caso}\\\\\mathbf{a)\ (9x^3)(3x^5)}\\\\\boxed{\mathbf{27x^8}}\\\\\\\mathbf{b)\ (11y^7)(8y^6)}\\\\\boxed{\mathbf{88y^{13}}}\\\\\\\mathbf{c)\ (18x^3y^4)(5x^4y^6)}\\\\\boxed{\mathbf{90x^7y^{10}}}$

$\textbf{Efect\'ua adecuadamente}\\\\\mathbf{a)\ 12(3x^2-4x+2)}\\\\\boxed{\mathbf{36x^2-48x+24}}\\\\\\\mathbf{b)\ (-6)(2x^3+5x^2-4x)}\\\\\boxed{\mathbf{-12x^3-30x^2+24x}}\\\\\\\mathbf{c)\ (-9)(-x^4+5x^2-3)}\\\\\boxed{\mathbf{9x^4-45x^2+27}}$
