Expanding the left side gives

which gives two solutions,

and

. But if

, then

, but this number isn't real, so

is an extraneous solution. Meanwhile if

, you get

, so this solution is correct.
"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.
Let, the first (smaller) number = x
Larger number = 8x
Then, 8x - x = 70
7x = 70
x = 70/7
x = 10
& 8(10) = 80
In short, Your Numbers would be, 10 & 80
Hope this helps!

-2.8
Answer:
The most helpful representation would be option C.
Step-by-step explanation:
The horizontal distance traveled corresponds to one of the roots of the quadratic equation.
h(x) = -0.01(x-150)(x+4)
In this case, option c presents the roots of the polynomial, which answers are
x = -4
x = 150
Since we are talking about positive distances, the first option gets discarded.
So the horizontal distance is x = 150 feet
Answer:
Algebraic expression ;

Step-by-step explanation:
4 is subtracted from r means the same as r decreased by 4
Subtracted = -
