Answer:
2-sqrt14/2, 2+sqrt13/2.
Step-by-step explanation:
What you do is you have to do the quadratic equation like it says in the problem.
x= −b± sqrtb^2 −4ac
/2a
.
a=-2, b=4, c=5.
x=-4±sqrt(4)^2-4(-2)(5)/2(-2).
x=-4±sqrt16+40/-4.
x=-4±2sqrt14/-2.
2-sqrt14/2, 2+sqrt13/2. is your answer once you have done everything.
It would be 574 over 1000, but it can be simplified to: 287 over 500. So the final answer simplified would be 287/500.
Answer:
(3,4)
I'm assuming this is how u wanted it to be solved if not give me more info on the problem and I'll redo it
Step-by-step explanation:
x= 3,y = 4
Answer:15
Step-by-step explanation:
27+x=42 alternate angles are equal
Collect like terms
x=42-27
x=15
