Answer:

-√7 = -2.64

Step-by-step explanation:

The polynomial function has roots. The first root is 3 and the second is √7.

When we have a square root that means that we get two roots from the same number but one is negative and the other is positive. For example, if we have:

√x² = ±x

Because we can have:

(-x)² = x², or

(x)²=x².

So a square root always gives us two answers, one negative and the other positive.

an air conditioner can cool a room that has a volume of up to 3,600 cubic feet. a room shaped like a rectangular prism is 15 fee
valentinak56 [21]

The length of the air conditioner is 24 feet.

Volume = 3600 feet ³

Width = 15 feet

Height = 10 feet

Length = Unknown

Therefore, the value of the length will be calculated thus:

Volume = Length × Width × Height

3600 = Length × 15 × 10

Length = 3600 / (15 × 10)

Length = 3600 / 150

Length = 24

The length is 24 feet
