Step-by-step explanation:
so, all 3 pieces together are 20 inches.
therefore,
x + 4x + 5x = 20
10x = 20
x = 2
so, the first piece is 2 inches long.
the second piece is 4×2 = 8 inches long.
the third piece is 5×2 = 10 inches long.

I hope im right !

Now, the "only" thing that remains to do is solving the above equation.
While making this problem I only made sure it has a solution. I didn't try to solve it myself and I didn't know it will end up with such "convoluted" polynomial. Sorry to everyone who tried to solve it... m(_ _)m
I think the best way to approach it is using the rational root theorem since we know that . Moreover we can deduce that since there is and .
After you succesfully solve it, you should get the answer .

There are 846 puzzles sold and including tax, it is $5 per puzzle. Multiply the amount of puzzles by cost and you get the total cost of all puzzles sold including tax.
Answer:
#6 is 66 degrees. since the two angles (angle 3 an angle 2) make a straight line, they have to add up to 180 degrees, and 180-114 is 66. #7 is 114 degrees because angles 3 and 1 are corresponding angles ( which means the anges are in the same relative position, which means angle 3 and 4 are equal)
