3 boxes times 40 = 120 + 3 = 143
or 3 boxes times 43 = 129
Like a to one to b uh I don’t know
Answer:
There's only 1 step. It is the second one, "Multiply 4 by 5 and multiply 4 by 3x"
Step-by-step explanation:
4(5 - 3x) =
4(5) - 4(3x) =
20 - 12x
You can't simplify further, so the second one is the right answer
Hope this helps! :)
The derivative of :
y = ( 2 x - 7 )³ - we will use the chain rule :
y = u³
y` = 3 u² · u`
y` = 3 ( 2 x - 7 )² · ( 2 x - 7 ) `
y ` = 3 ( 2 x - 7 )² · 2
y ` = 6 ( 2 x - 7 )²
