The formula is (number of sides-2)*180 over number of sides

Each angle for hexagon is 120degree because
(6-2)*180 over 6 equals to 120
So p is 120
For q:
2q=180-120
2q=60
q=60 over 2
q=30
P+Q=120+30
=150

Hello there!

$( (2^2*3^2x^2) - 25) \\ \\ Factoring: \boxed{36x2-25} \\ \\ (PROOF): \\ \\ (A+B) * (A-B) = \\
 A2 - AB + BA - B2 = \\
 A2 - AB + AB - B2 = \\
 A2 - B2 \\ \\$

Your final answer would be (<span> (6x + 5) • (6x - 5)).

Your correct answer would be (option d).

Write the equation for the line in slope intercept form

Helen [10]

Answer:

y = -2x -3

Step-by-step explanation:

The line crosses the y-axis at -3, so that is the y-intercept.

It has a "rise" of -2 units for each "run" of 1 unit, so the slope is -2. (For example, from point (-1, -1) to point (0, -3).)

The slope m and y-intercept b are used in the slope-intercept form of the equation of a line:

y = mx + b

For the values this line has, the equation is ...

y = -2x -3

!!!please for the love of God help me!!!

<h3>Given :-</h3>

$\\$

x=y-1
x+2y=8

$\\$

$\\$

Value of x
Value of y

$\\$

<h3>Solution:-</h3>

Let say it is first equation:-

x=y-1. . . . (1)

and this is second equation:-

x+2y=8 . . . . (2)

$\\ \\$

Simplifying 1 equation:-

x = y - 1
x +1 = y
y = x + 1

Put this value of y in second equation.

$\\$

$\dashrightarrow \sf \: x+2y=8$

$\\$

$\dashrightarrow \sf \: x+2(x + 1)=8$

$\\$

$\dashrightarrow \sf \: x+2x +2=8$

$\\ \\$

$\dashrightarrow \sf \: 3x +2=8$

$\\ \\$

$\dashrightarrow \sf \: 3x=8 - 2$

$\\ \\$

$\dashrightarrow \sf \: 3x=6$

$\\ \\$

$\dashrightarrow \sf \: x=6 \div 3$

$\\ \\$

$\dashrightarrow \sf \: x= \bf2$

$\\$

to find value of y :-

y = x + 1

y = 2 + 1

y = 3

$\\$

verification:-

$\\$

1 equation:-

x = y - 1

put value of x and y

2 = 3 - 1

2 = 2

LHS = RHS

Hence verified!

$\\$

2 equation:-

$\\$

x+2y=8

put value of x and y

2 + 2 × 3 = 8
2 + 6 = 8
8 = 8

LHS = RHS

Hence verified!

$\\$

Both equation verified!

.°. value of x and y is 2 and 3 respectively
