Answer:
C. In y^2-y=6, 6 should have been subtracted on both sides first.
Step-by-step explanation:
It is a quadratic equation so you subtract the 6 and create
y^2-y-6=0
Then you factor it to:
(y-3)(y+2)=0
The solutions then are:
y-3=0, y=3 and y+2=0, y=-2
{-2,3}
Answer:
Step-by-step explanation:
It means that you have to have pi in your answer. For example, if you were finding the area of a circle with a radius of 3, you would do (3)^2*pi and simplify it to just 9pi.
Answer: Answer is in the steps.
Step-by-step explanation:
No multiple of 7 can be a prime number because then it will have more than two factors.7 is a prime number because it has only two factors 1 and itself. For example, 14 is a multiple of 7 because 7 times 2 is 14. But now it 14 itself will not be a prime number because it has more than two factors which is 1,2,7 and 14.
