Answer:
7x-14
Explanation:
you must use the distributive property. to do this, you must multiply the value outside the parentheses (7) by the first term in the parentheses (x) and add that to the multiplication of 7 and the second term (-2). 7 multiplied by x is 7x, and 7 multiplied by -2 is -14. when you add these two values, you get 7x-14.
