Using quadratic formula
x = [-18 +-sq root (324 -4 *3*15)] / 2*3
x = [-18 +-sq root (144)]/6
x1 = (-18 + 12) / 6 = -1
x2 = (-18 -12) / 6 = -30/6 = -5

So $350 X 10 =$3500
Then, you add the initial $1500,
which means he now has $5000
The difference between $5000 and $4500 is $500,
<span>And $500 is 9% of $4500, </span>
So the deal is equivalent to a yearly interest of 9%
<span>Hope this helps ! :)</span>
Answer:
the surface area of the larger prism is or about 2.8 times the surface area of the smaller prism.
Answer:
x = -2.5 ± √14.25
Step-by-step explanation:
Add 5x to prepare for "completing the square."
x² +5x = 8
Add the square of half the x-coefficient:
x² +5x + 2.5² = 8 + 2.5²
(x +2.5)² = 14.25
Take the square root.
x +2.5 = ±√14.25
Subtract 2.5.
x = -2.5 ± √14.25 ≈ {-6.27492, 1.27592}
