Answer:
Create a table.
Plug values into the equation to complete the table.
Use the table to plot points on the graph.
Draw lines through the points on your graph.
The graph should look linear because there is an x that doesn't have a power greater than or less than 1.
8n+6 is equal to the phrase 6 more than the product of 8 and n
As you see this is a right angle, so the sum of the two angles = 90°
So,
(x + 42) + 3x = 90°
Remove the parentheses:
x + 42 + 3x = 90
Combine like terms:
4x + 42 = 90
Subtract 42 on both sides:
4x = 48
Divide 4 on both sides:
x = 12
~
If the sides are in the ratio of 11:16:24, it means that they are all multiples of a same number x, according to these factors.
So, the shorter side is 11x feet long, the middle one is 16x feet long, and the longest side is 24x feet long.
This means that the perimeter is
feet long. But we know that this is 510 feet, so we have
.
So, the three sides are 110, 160 and 240 feet long.
To find the area of a triangle knowing its three sides, you can use Heron's formula, which states that, if 
is half the perimeter of the triangle whose sides are 
, the area 
is given by
In our case, 
so the formula becomes
Step-by-step explanation:
first ..
subtract 2 on both sides 2-2...2-y
then you should have 1/2x =y-(-2) then divide
