What are the solutions of 3x2 + 6x + 6 = 0 –2 ± i –2 ± 2i –1 ± i 1 ± i

velikii [3]

C) Quick way:

3x^2+6x+6=0 ---> x^2+2x+2=0,

sum of solutions is the 'x' coefficient multiplied by -1: (-1+i)+(-1-i)=-2-->2
Product is the independent term: (-1+i)(=1+i) = (-1)^2-i^2 = 1+1=2

The floor in the tool room measures 13 feet 3 inches by 11 feet 5 inches. What is the total area of the room in square feet? (Re

brilliants [131]

We have The floor in the tool room measures 13 feet 3 inches by 11 feet 5 inches.

Let us convert inches to feet since we want the area in square feet.

We know that 1 inch = 0.0833333 feet .

Therefore, we have

3 inches = 0.25 feet

5 inches = 0.42 feet

Thus, we have the below dimension in feet

Length = 13 feet 3 inches = 13+0.25 = 13.25 feet

Width = 11 feet 5 inches = 11+0.42 = 11.42 feet

Hence, area of the room is given by

$A= \text{Length} \times \text{width}
\\
A=13.25 \times 11.42\\
\\
A=151.3 \text{ square feet}\\
A\approx 151 \text{ square feet}\\$

a is the correct option.
