Câu hỏi: Cho $\int\limits_{0}^{2}{f\left( x \right)}\text{d}x=3$ và $\int\limits_{0}^{2}{g\left( x \right)}\text{d}x=7$, khi đó $\int\limits_{0}^{2}{\left[ f\left( x \right)+g\left( x \right) \right]}\text{d}x$ bằng
A. $10$.
B. $16$.
C. $-18$.
D. $24$.
A. $10$.
B. $16$.
C. $-18$.
D. $24$.
$\int\limits_{0}^{2}{\left[ f\left( x \right)+g\left( x \right) \right]}\text{d}x=\int\limits_{0}^{2}{f\left( x \right)}\text{d}x+\int\limits_{0}^{2}{g\left( x \right)}\text{d}x=3+7=10$.
