Answer:
A. (9,2)
Step-by-step explanation:
Answer:
Let the consecutive numbers be x and x+1
given
(x+1)^2=19+9x
x^2+2x+1=19+9x
like terms together
x^2+2x-9x+1-19=0
x^2-7x-18=0
factorize the quadratic equation to get the value of x
(x-9)(x+2)=0
x=9 and x=-2
we reject the second option
the answer is x=9 and x=9+1=10
x=9 and x=10
