Three! -7/9, -1/4, and -4/3

3 0

Answer with Step-by-step explanation:

The fundamental theorem of algebra states that every non-constant single-variable polynomial with complex coefficients has at least one complex root. This includes polynomials with real coefficients, since every real number can be considered a complex number with its imaginary part equal to zero.

Hence, the given polynomial equation has atleast 1 real root and atmost 3 real roots

(9x + 7)(4x + 1)(3x + 4) = 0

On solving this, we get

9x+7=0  or  4x+1=0  or 3x+4=0

i.e.  x= -7/9  or  x= -1/4  or  x= -4/3

As we can see all the roots are real

Hence, number of real roots are:

3

garri49 [273]

Answer:

86

Step-by-step explanation:

48÷6 [-52 ÷2 {4 - 3 (2 - 15÷3)}] \\ 8[-52 ÷2 {4 - 3 (2 - 15÷3)}] \\ 8[-52 ÷2{1 (2 - 15÷3)}] \\ 8[ - 2.5{ (2 - 15÷3)}] \\ 8[ - 2.5{ ( - 13÷3)}] \\ 8[ - 2.5{ (  - 4.3)}] \\ 8[10.75 { }] \\  = 86

HURRY I NEED HELP!!!!!!!!!!!!! A circle is drawn within a square as shown.
Anton [14]
The width of the square is 7 cm. This is also the diameter of the circle.

To find the area of the square, you do 7², which is 49 cm². 

To find the area of a circle, you do πr².

The radius is half the diameter, so it's 7 ÷ 2, which is 3.5 cm.

π3.5² ≈ 38.4845100065 cm².

The shaded region is the area of the square minus the area of the circle.  

49 - 38.4845100065 = <span>10.5154899935, but because you're using 3.14 to approximate pi, the closest answer is 10.54 cm</span>².

The answer is 10.54 cm².

Answer:

b =  \sqrt{65}

Step-by-step explanation:

{b}^{2}  +  {4}^{2}  =  {9}^{2}  \\  {b}^{2} + 16 = 81 \\  {b}^{2}   = 81 - 16 \\  {b}^{2}  = 65 \\ b =  \sqrt{65}

I hope I helped you^_^
