The correct answer for the first question is: $x^{\wedge }2-7x-10$<br /><br />Explanation: To find the product of $(x-2)(x+5)$, we can use the distributive property (also known as the FOIL method). <br /><br />$(x-2)(x+5) = x(x+5) - 2(x+5)$<br />$= x^2 + 5x - 2x - 10$<br />$= x^2 + 3x - 10$<br /><br />Therefore, the correct answer is $x^{\wedge }2-7x-10$.<br /><br />For the second question, the correct answer is: a. Line segment<br /><br />Explanation: A line joining two endpoints is called a line segment. A line segment is a part of a line that is bounded by two endpoints. It has a finite length and is represented by the symbol $\overline{AB}$, where $A$ and $B$ are the endpoints.
