(3x^4+2x^3-7)+(4x^6-5x^3+9) Which of the following expressions is equivalent to the expression above? 4x^6+3x^4-3x^3+2 4x^6+3x^4+7x^3+2 4x^6+3x^4-5x^3+2 D) 7x^10-3x^3+2

To find the equivalent expression, we need to combine like terms in the given expression:<br /><br />$(3x^{4}+2x^{3}-7)+(4x^{6}-5x^{3}+9)$<br /><br />Combining like terms, we get:<br /><br />$4x^{6}+3x^{4}-3x^{3}+2$<br /><br />Therefore, the equivalent expression is:<br /><br />$4x^{6}+3x^{4}-3x^{3}+2$<br /><br />So, the correct answer is:<br /><br />$4x^{6}+3x^{4}-3x^{3}+2$
