It's easiest to start with the point-slope form of an equation,
, where m is the slope and
is the point given.
We have m = 3,
, and
.
We plug in these values to get
.
We now rearrange to get this into slope-intercept form,
, by solving for y.
we have,
14x+8+6x+12=180 {interior angle}
or, 20x+20= 180
or, 20x= 180- 20
or, x= 160/20
:. x= 8
Now,
14x+8= 14.8+8
= 112+8 =120
6x+12= 6.8+12
= 48+12 = 60
Answer:
45units^2
Step-by-step explanation:
Break the polygon into two shapes. A rectangle and a triangle.
The area formula for a rectangle is A=L•W or
Area = Length x Width. Counting the units for length and width is 9 x 2. Which would equal 18units.
Now for the triangle, the formula is A=1/2 (b•h)
The base is 9 and Height is 6.
9 • 6 = 54
Since a triangle is half the area of a rectangle you divide 54 by 2. Area for triangle is 27.
Now add the rectangle area and triangle area.
18+27=45
Area=45 units ^2
X^2 + 5 = 5 + x^2 will give you the same answer. Also know as the commutative property. Answer is (3)
Hi there!
To find the percent of change we can use the following formula:
Let's fill in our data
Subtract
Divide
And finally multiply
Hence, the percent of change is negative 20%.
