Find the value of x.<br> 3x +7<br> D<br> 2x + 7<br> 3x 16
Mashcka [7]

Answer:

sum of interior angle of a triangle is 180 degree

so,

3x +7 + 2x+7 +3x+6 = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = 160/ 8

x = 20

15 When (x)(x - 5)(2x + 3) is expressed as a
wlad13 [49]

Given:

The polynomial is

x(x-5)(2x+3)

To find:

The standard form of the polynomial and correct statement for the polynomial.

Solution:

Let, P(x)=x(x-5)(2x+3)

On multiplication, we get

P(x)=(x^2-5x)(2x+3)

P(x)=x^2(2x)+x^2(3)-5x(2x)-5x(3)

P(x)=2x^3+3x^2-10x^2-15x

P(x)=2x^3-7x^2-15x

Here,

Constant term is 0, leading coefficient is 2, degree is 3 and number of terms is 3.

Therefore, the correct option is 2.

Write an inequality to represent the graph below.
Yanka [14]

Answer:

The answer to your question is letter C

Step-by-step explanation:

Process

1.- Find two points of the line

A ( 0, -3)   B ( 2, 2)

2.- Find the slope of the line

    m = \frac{y2 - y1}{x2 - x1} = \frac{2 + 3}{2 - 0}

    m = \frac{5}{2}

3.- Find the equation of the line

    y - y1 = m(x - x1)

    y + 3 = 5/2(x - 0)

    y + 3 = 5/2 x

    y = 5/2 x - 3

4.- Convert the line to an inequality, we want the upper area so use ">"

    y > 5/2 x - 3
