Answer:
The answer is b) 2(2x-4) and c)
Step-by-step explanation:
Okay lets try a) 2(2x-6)
2 x 2x - 2 x 6= 4x-12
b) 2(2x-4)
2 x 2x - 2 x 4=4x-8
c) : x-8+3x
x+3x-8=4x-8
So first you have to do 12-2 since it's in parenthesis. It is 10. 5+4 is 9, and 9 times 10 is 90. 3 squared is 9, then you divide 90 by 9. The answer is 10.
6, 7 or 8 oranges
x = 19/3
30 - 11 = 3x
3x = 19
hope it helps!
