I think it's the third one b/c
the associative property states that it doesn't matter how you group the
numbers in parenthesis in addition.
x + 7 = 2(3x - 4) Remove the brackets
x + 7 = 2*3x - 4*2
x + 7 = 6x - 8 Subtract 7 from both sides.
x + 7 - 7 = 6x - 8 - 7
x = 6x - 15 Subtract 6x from both sides
x - 6x = - 15
-5x = - 15 Divide by -5
-5x/-5 = -15/-5
x = 3

Answer:
log 337
Using log a x = ln x /ln a

= 2.52763
Hope this helps.
Answer:
56 cm
Step-by-step explanation:
By using a^2 + b^2 = c^2, you can determine that the slanted line of the trapezoid is ~11.6, which rounds to 12 cm.
12 + 14 + 24 + 6 = 56
