Since both numbers are negative we know that the product will be positive and when something is time 1.5 that is the same as a 50% increase so that is adding half of the original number (4) so the final answer is 6 (4+(half of 4))=6

Answer:
martina is 22 feet below sea level
Step-by-step explanation:
Marina goes down 20 feet
then rises 7 feet which is 20 - 7 = 13

20 - 7 + 9 =22
Martina is 22 feet below sea level.
Answer:
Solutions will be unreal
Step-by-step explanation:
Given the quadratic equation ax^2+bx+c
The discriminant of the function determines its nature of its root
Discriminant D = b^2-4ac
If D <0, it shows that the roots of the equation will be a complex value. since D is less than 0 and the square root of a negative number does not exist. Hence, the solutions will be unreal
