-3 and 4 cannot be the values of x in the given expression

The expression is given as:

\frac{(x^2-x-6x^2-8x+16)}{(x^2-x-12)}

Start by equating the denominator to 0

x^2 - x - 12 = 0

Expand the above equation

x^2 - 4x + 3x - 12 = 0

Factorize the equation

x(x - 4) + 3(x - 4) = 0

Factor out x - 4

(x + 3) (x - 4) = 0

Split

(x + 3)= 0\ or\  (x - 4) = 0

Remove brackets

x + 3= 0\ or\  x - 4 = 0

Solve for x

x =- 3\ or\  x = 4

Hence, -3 and 4 cannot be the value of x in the given expression

Calculate each unknown side length. Round your answer to the nearest tenth.
Drupady [299]
To answer this you need to use the Pythagorean theorem, the first part it 4^2+x^2=7^2 so the answer to the bottom x is 5.7. Your next step is to do the Pythagorean theorem for the whole triangle so your equation would be 10^2 + 5.7^2= x^2 once you solve that you will get 132.49 which you need to take the square root of. Once you will do that you will find the other x = 11.5

Use the given angle measures to find the indicated
mina [271]

Answer:

x = -9°

m∠A = 37°

Step-by-step explanation:

(8-5x) + (10-3x) = 90

8-5x + 10-3x = 90

18-8x = 90

-8x = 72

x = -9°

m∠A = 10- (-9*3) =

10-(-27) = 37°

Emily has 300 books. if frank were to double the number of books that he now owns, he would still have fewer than Emily has
Alex_Xolod [135]
This statement is false. 
If he were to double the amount that Emily has to get franks, franks would have more. 
Look :)
Emily's = 300
Frank's = 300 x 2 = 600

now...
Emily's = 300
Frank's = 600

So frank has more! NOT fewer.
