Answer:
32 - 9 x (don't know what you want simplify or solve for x) x = 32/9
Step-by-step explanation:
Simplify the following:
20 - 3 (3 x - 4)
-3 (3 x - 4) = 12 - 9 x:
12 - 9 x + 20
Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:
(20 + 12) - 9 x
20 + 12 = 32:
Answer: 32 - 9 x
_________________________________
Solve for x:
20 - 3 (3 x - 4) = 0
-3 (3 x - 4) = 12 - 9 x:
12 - 9 x + 20 = 0
Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:
(20 + 12) - 9 x = 0
20 + 12 = 32:
32 - 9 x = 0
Subtract 32 from both sides:
(32 - 32) - 9 x = -32
32 - 32 = 0:
-9 x = -32
Divide both sides of -9 x = -32 by -9:
(-9 x)/(-9) = (-32)/(-9)
(-9)/(-9) = 1:
x = (-32)/(-9)
Multiply numerator and denominator of (-32)/(-9) by -1:
Answer: x = 32/9
I hope this is the answer:)
3x-x+2=4
sorry... this answer is VERY wrong
Since the perimeter of the square is 28ft, the side length of the square is 7ft.
Hence, the area of the square is 49 square feet.
