The linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)

The linear factors of polynomials are the first-degree equations that act as the building block for the simple or complex higher-order polynomials.

Given that, a polynomial 2x⁴+13³+27x²+13x-15, the remainder upon division with x²+4x +5 is zero,

That means, x²+4x +5 is a factor of the given polynomial,

On diving 2x⁴+13³+27x²+13x-15 by x²+4x +5 we get 2x²+5x+3 as quotient that means,  x²+4x +5 and 2x²+5x+3 are the factors of the polynomial,

On factorizing both the factors we get,

(2x+3)(x+1)(x+2+i)(x+2-i)

Hence, the linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)

Answer:

Y-intercept: (0,-0.7)

X-intercept: (-1.2,0)

Explanation:

The Y-intercept is the spot where the line crosses the Y axis (the vertical axis). This always occurs where X=0. For this problem the Y value at this point is -0.7. So, for the coordinates (X,Y) X is 0 and Y is -0.7 so it is (0,-0.7)

The X-intercept is the spot where the line crosses the X axis (the horizontal axis). This always occurs where Y=0. For this problem the X value at this point is -1.2. So, for the coordinates (X,Y) X is -1.2 and Y is 0 so it is (0,-0.7)

Answer:

let the unit digit be x

and the tens digit be y

so x+y = 9 ---> y = 9-x

the number is 10y+x

the number reversed is 10x + y

3(10y+x) = 8(10x + y)

30y + 3x = 80x + 8y

22y = 77x

2y = 7x

2(9-x) = 7x

18 - 2x = 7x

18=9x

x=2

y=7

the number is 72

check:

number is 72

reverse is 27

is 3(72) = 8(27)

Answer:

The enlarged picture will have a width of 35.8 cm

Step-by-step explanation:

We can solve this question by proportions, using rule of three.

When the length is of 15 centimeters, the width will be of 14.5 centimeters. What is the width when the length is 37 centimeters?

15 cm - 14.5 cm

37 cm - x

Applying cross multiplication

[tex]15x = 14.5*37[/tex]

[tex]x = \frac{14.5*37}{15}[/tex]

[tex]x = 35.8[/tex]

The enlarged picture will have a width of 35.8 cm

Answer:

36.25 cm

Step-by-step explanation:

37.5 divided by 15 is 2.5 then multiply 14.5 by 2.5 and your answer will be 36.25 cm.

Answer:

0.25 is a decimal and 25/100 or 25% is the percentage for 2/8.

Step-by-step explanation:

The result is: 0.25 and 25% is 2/8 as a decimal and percent.

Here, we have,

given that,

the fraction is:  2/8

now, we have to write as a decimal and percent.

so, we get,

2/8

[ dividing both numerator and denominator by 2 ]

= 1/4

= 0.25

so, we get, 0.25 is a decimal.

now, we have,

0.25 = 25/100 = 25%

so, we have, 25/100 or 25% is the percentage for 2/8.

Answer: g = 13 / Thats the output

Step-by-step explanation:

g = 25 - 3r

Its telling you the r is 4 since its the input.

g = 25 - 3 ( 4 )   see!! just plug in the number

Now Solve

g = 25 - 12

g = 13

Answer:

g = 13

Step-by-step explanation:

since r = 4, you make the equation :

g=25-3(4)

first you multiply 3 and 4 and you get 12

g=25-12

and 25 - 12 is 13 which equals :

g = 13

Answer:

a. Doors = 31 doors

b. Windows =155 windows

Step-by-step explanation:

Given the following data;

Ratio D:W = 1:5 = 1 + 5 = 6

Total number of doors and windows = 186

Ratio of doors to windows = 1/6

Ratio of windows to doors = 5/6

To find the ratio of the doors;

Doors = 1/6 * 186

Doors = 186/6

Doors =31 doors

To find the ratio of windows;

Windows = 5/6 * 186

Windows = 930/6

Windows =155 windows
