Answer:

Step-by-step explanation:

The opposite side to angle B is 4. It is the line AC. AC is not connected in any way to <B

The adjacent side is one of the two sides making up <B. It is 3.

Tan(B) = opposite / adjacent

Tan(B) = 4/3

<B = tan-1(4/3)

<B = 53.13

Simplify completely..........

vitfil [10]

Answer:

$\frac{x}{x-1}$

Step-by-step explanation:

$\frac{3x^2 - 1}{x^2 - 1} - \frac{2x + 1}{x + 1}$ $[ \ x^ 2- 1 = (x-1)(x + 1) \ ]$

$= \frac{3x^2 - 1}{(x-1)(x + 1 )} - \frac{2x + 1}{x + 1}\\\\=\frac{(3x^2 - 1)-(2x + 1)(x-1)}{(x + 1)(x-1)}$ $[\ Taking \ LCM \ ]$

$= \frac{(3x^2 - 1)- (2x^2 - 2x + x - 1)}{(x+1)(x-1)}\\\\=\frac{3x^2 - 1 - 2x^2 + x + 1 }{(x+1)(x-1)}\\\\=\frac{x^2 +x}{(x+1)(x-1)}\\\\=\frac{x(x+1)}{(x+1)(x-1)}\\\\=\frac{x}{x-1}$

Finding LCM :

Example :

$\frac{1}{6} + \frac{1}{3}$

6 = 2 x 3

3 = 1 x 3

$\frac{1}{2 \times 3} + \frac{1}{ 3}$ $= \frac{1}{2 \times 3} + \frac{1 \times 2}{ 3 \times 2}$

[ To make the denominators same : the second fraction is multiplied and divided by 2 ]

Similarly :

$(x^2 - 1 ) = (x -1)(x+1)\\\\(x + 1) = 1 \times (x + 1)$

Same rule we applied : multiplied the numerator and denominator of the second term with ( x - 1 )

Therefore the second term becomes ,

$\frac{2x + 1}{x + 1} = \frac{(2x + 1)(x - 1)}{(x + 1)( x - 1)}$

Image Attached, Complete the square. Fill in the number that makes the polynomial a perfect-square quadratic. Will give Brainlie

AnnZ [28]

Answer:

169

Step-by-step explanation:

You should know that the middle number with the x is double the original number not in expanded form. You should also know that in the expanded form, the last number is the square of the original number. So square(26/2) = 169.
