The square of a positive number is equal to its triple added to 28. What is this number?​
sashaice [31]

hi brainly user! ૮₍ ˃ ⤙ ˂ ₎ა

\huge{ \rm{Answer:}}

The roots of the equation are 7 and -4, because 7 - 4 = 3 and 7. - 4 = -28

Step-by-step explanation:

The positive number is equal to 7.

Assuming that the number is equal to "x" we have:

\begin{gathered}x^2 = 3x + 28\\\\x^2 - 3x - 28 = 0\\\\a = 1\\\\b = -3\\\\c = -28\\\end{gathered}

By the sum and product method, we have:

\begin{gathered}S = -b / a\\\\S = -(-3) / 1\\\\S = 3\\\\\end{gathered}

\begin{gathered}P= c / a\\\\P = 28 / 1\\\\P = 28\\\\\end{gathered}

worty [1.4K]
I'm assuming this is a yearly interest.

2500*.04=100
7500*.05=375

so that would be $475 earned from interest
