2/3 x n + 4 = 7.
I believe it's this equation.
Using m = (y2-y1)/(x2-x1)
(2-3)/(4-2)
-1/2
The slope is -1/2. b.
Let's set the first angle as x, the second angle is then 4x, and the third angle is (x+4x)+15, which is 5x+15
the three angles make a sum of 180: x+4x +5x+15=180
10x=165
x=16.5
the second angle is 4x=4*16.5=66
Answer:
First solve for x
then substitute
Step-by-step explanation:


2x + 6 = 3y + 6
2x = 3y

If
then
=

Hey there,
Length = 4x
Width = 3x
Perimeter = 112 inches
4x + 3x + 4x + 3x = 112 inches
14x = 112 inches
x = 112 inches / 14
= 8 inches
Length = 8 inches x 4
= 32 inches
Width = 8 inches x 3
= 24 inches
Hope this helps :))
