Use the rational root theorem
a0=16,  an=1

The dividers of a0: 1,2,4,8,16   The dividers of an:1
Therefore check the following rational numbers: +- 1,2,4,8,16/1
4/1 is a root of the expression, so factor out x-4,

compute (x^4+13x^3-64x^2-20x+16)/(x-4) to get the rest of the equation: 
x^3+17x^2+4x-4

=(x-4)(x^3+17x^2+4x-4)/x-4

which will leave you with answer B
x^3+17x^2+4x-4

Why is the product of two rational numbers always rational?
Mice21 [21]

Let a/b and c/d represent two rational numbers. This means a, b, c,and d are INTEGERS , and b and d are not 0. The product of the numbers is ac/bd , where bd is not 0. Both ac and bd are INTEGERS , and ​ bd ​ is not 0. Because ​ ac/bd ​ is the ratio of two INTEGERS, the product is a rational number.

\frac{a}{b}\cdot \frac{c}{d}= \frac{a\cdot c}{b\cdot d}=\frac{e}{f},\,\,\,\,e,f\in\cal{Z}

does anyone know how to solve (and find the domain) a math problem like this: (7^5-x)^6-x = 49 (pls include explanation I have a
Naily [24]

Answer:

his is the format of the straight-line equation,

Where, y = mx + c

Here, m = slope

c = y-intercept.

You usually get coordinates, and after solving, we get our result as an equation of the line.

Hope this helps!

Read it and solve it for me
AnnyKZ [126]

Answer:

a. y + 9 + x + y + x + 4 + x + 5 = 2x + 2y + 18

b. 30.4cm

c. Area of big rectangle = 9y cm², Area of small rectangle = 4x cm²

d. a = 9y + 4x

e. a = 38.8

Step-by-step explanation:

a. Perimeter = y + 9 + x + y + x + 4 + x + 5

                     = x + x + y + y + 9 + 4 + 5

                     = 2x + 2y + 18

b. 2x + 2y + 18 = 2(3.4) + 2(2.8) + 18

                        = 6.8 + 5.6 + 18

                        = 30.4cm

c. Formula for area of rectangle: length × breadth

Area of big rectangle = 9 × y

                                    = 9y cm²

Area of small rectangle = 4 × x

                                       = 4x cm²

d. a cm² = (9y + 4x)cm²

e. a = 9y + 4x

      = 9(2.8) + 4(3.4)

      = 25.2 + 13.6

      = 38.8
