<span>8d – 4d – 6d – 8 = 2d
Combine common terms:
-2d - 8 = 2d
Add 2d to both sides:
-8 = 4d
Swtich sides:
4d = -8
Divide both sides by 4:
d = -2
Answer: - 2

The answer would be 42 degrees because the total of a triangle is 180 degrees. So you would subtract 180 and 42 (180-42) and that gives you 138 and since the two angles that are touching are the same 
 
        
             
        
        
        
Answer:
Out of these careers, an engineer would be the most geometric involved career.
Step-by-step explanation:
This answer is true through the process of elimination. A stockbroker focuses on economy in order to choose the right stock. A statistician focuses on graphing and statistics in terms of math. An accountant is focused on simple math in order to deduct and add to the sum of the money. The engineer has to use geometry in order to design plans for constructions.
 
        
             
        
        
        
Answer:
y = 4x+23
Step-by-step explanation:
The slope intercept form of a line is 
y = mx+b where m is the slope and b is the y intercept
y = 4x+b
Substitute the point into the equation
7 = 4(-4)+b
7 = -16+b
Add 16 to each side
7+16 = b
23 = b
y = 4x+23
