Multiply the bracket by 5
I used PEMDAS
P= parenthesis
E= exponents
M=multiplication
D= division
A= addition
S= subtraction
7r+2= 5(r-4)
7r+2= 5r-20
Move 5r to the left hand side . Positive 5r changes to negative 5r
7r-5r+2= 5r-5r-20
2r+2=- 20
2r+2-2= -20-2
Move positive 2 to the right hand side. Changes to negative -2
2r+2-2= -20-2
2r= -22
Divide by 2 for 2r and -22
2r/2= -22/2
r= -11
Answer is r= -11
The coefficient 7 means that the length is 7 times the width
<h3>How to interpret the coefficient?</h3>
The given parameters are:
Width = x
Length = 7x
Area = 7x^2
We have:
Length = 7x
Substitute Width = x in Length = 7x
Length = 7 * Width
This means that the length is 7 times the width

Step-by-step explanation:
75 -----> 75 out of 360
360-75=285
285-75 will be divided by 2
210 divided by 2 equals 105
105 is the measure of the angle I think (lmk if its wrong)
