Answer: (-9 ± 3√5) / 2

Step-by-step explanation:

Since our equation is in the form of ax² + bx + c = 0, we'll use the quadratic formula to solve the equation, plugging our values in:

(-9 ± √9²-4(1)(9)) / 2(1)
(-9 ± √81 - 36) / 2
(-9 ± √45) / 2

Here, we can simplify √45 by finding pairs of factors that equal 45, and have one of the factors be able to be square rooted:
(-9 ± √9·√5) / 2
(-9 ± 3√5) / 2

For her semester project, an art student was required to complete an oil painting that was at least 5 square feet in area. If the student wanted to make a painting that was 3 3/4feet wide, what is the minimum height (in feet) that it could be?

Answers

The area of the figure would have to be:
Height × Width

The minimum area would be:
5×5=25 square ft.

To find the minimum height,we devide the area by it's width.

If the painting is 3 3/4 feet wide,the minimum height would have to be:
25÷3 3/4
=25/3×3/4
=25/4 or 6 1/4 ft.

Thus the answer would be:25/4 or 6 1/4 ft.

Hope it helps!

The minimum height would be roughly 1.67 feet.
