The answer is 14.
a number divided by 1/2 will equal that number times 2
7*2 = 14
correct answer is option d.
<u>Step-by-step explanation:</u>
Here, we have The following expression to check Which of the following is a polynomial with roots: −square root of 3 , square root of 3, and 2 :
<u>a. x3 + 3x2 − 5x − 15
</u>
For
