9*(5-y)
nine times is 9* and the difference of 5 and y is 5-y
![xy=60\\ x+y=-2\\\\ xy=60\\ x=-y-2\\\\ (-y-2)y=60\\ -y^2-2y-60=0\\ y^2+2y+60=0\\ y^2+2y+1+59=0\\ (y+1)^2=-59 ](https://tex.z-dn.net/?f=xy%3D60%5C%5C%0Ax%2By%3D-2%5C%5C%5C%5C%0Axy%3D60%5C%5C%0Ax%3D-y-2%5C%5C%5C%5C%0A%28-y-2%29y%3D60%5C%5C%0A-y%5E2-2y-60%3D0%5C%5C%0Ay%5E2%2B2y%2B60%3D0%5C%5C%0Ay%5E2%2B2y%2B1%2B59%3D0%5C%5C%0A%28y%2B1%29%5E2%3D-59%0A)
There are no such numbers in real numbers.
Do you perhaps want a solution in complex numbers?
Answer:
A. x=0 and x=4
Step-by-step explanation:
The roots of a quadratic function are the x intercepts of the parabola. In this case, the roots are 0 and 4 because the parabola intercepts the x axis twice in these points.
Your answer is A. x=0 and x=4
Hope I helped!
The answer is B
A. 6(a+5)
=6a+30 not equivalent to 6a+15
B.3(2a+5)
=6a+15 is equivalent
C.3(3a+12)
=9a+36 not equivalent
D.6(a+12)
=6a+72 not equivalent
So your answer is B
