The factors of 4x^2 +8x-5 are (2x-1) and (2x+5)
2(x+y)=24
2x=y
Use substitution. If y=2x, than we can substitute 2x for it in the other equation, because x and y equal the same things in both equations.
So using that we get 2(x+2x)=24
SIMPLIFY
2(3x)=24
DISTRIBUTE
6x=24.
DIVIDE: x=4.
If we substitute x into the original equations we get x=4 and y=8. Those are your two numbers.
Have a nice day! :)
Answer:
-3/22
Step-by-step explanation:
Mulitiply straight across. Num * num/ denom * denom.
Now you have -6/44. Divide both by 2 to simplify into simipliest form.
Since it says when Added they are a negative and when multiplied they are positive, we know our two numbers are negative.
think of all multiples of 24
6 and 4
8 and 3
12 and 2
24 and 1
however, none of our choices here would be correct.
and we know that
