Answer:

$.$

Step-by-step explanation:

<h2>IdEnTiTy UsED</h2>

${x}^{2} - {y}^{2} = (x + y)(x - y)$

$(x - 5)(x - 5)$

=(x-5)²

$(3x - 2)(3x + 2)$

${(3 x)}^{2} - {(2)}^{2}$

$= 9 {x}^{2} - 4$

$(1+x)(1+x)$

= (1+x)²

(X^2+ x– 12) (x^2+ 10x + 25)

yulyashka [42]

Solution:

(x² + x – 12)(x² + 10x + 25)
=> (x⁴ + 10x³ + 25x²) + (x³ + 10x² + 25x) + (-12x² - 120x - 300)
=> x⁴ + 10x³ + 25x² + x³ + 10x² + 25x - 12x² - 120x - 300
=> x⁴ + (10x³ + x³) + (25x² + 10x² - 12x²) + (25x - 120x) - 300
=> x⁴ + (11x³) + (23x²) + (-95x) - 300
=> x⁴ + 11x³ + 23x² - 95x - 300

The only term that has a x-variable is "-95x".

The coefficient of x is -95.

Find the value of X.

pychu [463]

Answer:

Solution,

Theorem:

The angle bisector theorem states that if a ray bisects an angle of a triangle,then it divides the opposite side into two segments that are proportional to other two sides.

By the theorem,

$\frac{24}{9x - 9} = \frac{32}{6x + 6} \\ or \: 24(6x + 6) = 32(9x - 9) \\ or \: 144x + 144 = 288x - 288 \\ or \: 144x - 288x = - 288 - 144 \\ or \: - 144x = - 432 \\ or \: x = \frac{ - 432}{ - 144} \\ x = 3$

hope this helps...

Good luck on your assignment..

A textbook store sold a combined total of 289 sociology and math textbooks in a week. The number of math textbooks sold was 65 l

erica [24]

Answer:

Contradictrion

Step-by-step explanation:

First write an equation. If the total is 289, then that goes one the right side of the =. Sociology textbooks will be x. If there were 65 less than x, it will be 65-x. Lets set it up:

x + 65 -x =289

Then combine like terms.

65 = 289

There are no values of x that make the equation true. The input is a contradiction.
