From the quadratic equation 3x² + X - 5 = 0, find alpha square plus beta square​
timama [110]

Answer:

  α² +β² = 3 4/9

Step-by-step explanation:

Assuming α and β are solutions to the equation, it can be factored as ...

  (x -α)(x -β) = 0

Expanding this, we get ...

  x² -(α +β)x +αβ = 0

Dividing the original equation by 3, we find ...

  x² +(1/3)x -5/3 ≡ x² -(α+β)x +αβ   ⇒   (α+β) = -1/3, αβ = -5/3

We know that the square (α+β)² can be expanded to ...

  (α +β)² = α² +β² +2αβ

  α² +β² = (α +β)² -2αβ . . . . . . subtract 2αβ

Substituting the values for (α+β) and αβ, we find the desired expression is ...

  α² +β² = (-1/3)² -2(-5/3) = 1/9 +10/3 = 31/9

  α² +β² = 3 4/9

Use the grouping method to factor the polynomial below completely 3x^3+9x^2+5x+15​
Tomtit [17]

Answer:

(x+3)( 3x^2 +5)

Step-by-step explanation:

3x^3+9x^2+5x+15​

Split into two groups

3x^3+9x^2     +5x+15​

Factor 3x^2 out of the  first group and 5 out of the second group

3x^2 ( x+3)  + 5(x+3)

Factor out x+3

(x+3)( 3x^2 +5)

What is the surface area of the rectangular<br> prism shown by the net?
brilliants [131]

Answer:

80

Step-by-step explanation:

There are four 4 by 3 rectangles, so I did 4x3 and got 12, then multiplied by 4 to get 48.  There are also two 4 by 4 squares, so 4x4=16 and 16x2=32

32+48=80

Find the area of the composite figure.
irga5000 [103]

Answer:

Option C, 488 square centimeters

Step-by-step explanation:

<u>Step 1:  Determine the area of the rectangle</u>

A = l * w

A = 22\ cm * 17\ cm

A = 374\ cm^2

<u>Step 2:  Determine the area of the triangle</u>

A=\frac{h*b}{2}

A=\frac{19\ cm * (22\ cm-10\ cm)}{2}

A=\frac{19\ cm * (12\ cm)}{2}

A=\frac{228\ cm^2}{2}

A=114\ cm^2

<u>Step 3:  Determine the total area</u>

A_{total} = 374\ cm^2 + 114\ cm^2

A_{total} =488\ cm^2

Answer:  Option C, 488 square centimeters
