A) \[\sqrt{2}(\sqrt{5}+\sqrt{7})cm\]
B) \[\sqrt{5}(\sqrt{2}+\sqrt{7})cm\]
C) \[\sqrt{2}(\sqrt{7}-\sqrt{5})cm\]
D) \[\sqrt{7}(\sqrt{2}+\sqrt{2})cm\]
Correct Answer: A
Solution :
In \[f(p)\] In \[p(x)={{x}^{2}}+3x-2\] \[\Rightarrow \] \[p(-1)={{(-1)}^{2}}+3(-1)-2=(-4)\] \[p(-1)=-4\] \[\Rightarrow \]You need to login to perform this action.
