8 0

Answer:

6 minutes and 29 seconds

Step-by-step explanation:

Subtract 30 from 59 to make it a bit easier, than add that 30 to 1 minute and 30 seconds and you would get 2 minutes exact. Then add the 4 minutes and you get 6. Also remember the extra 29 seconds and add that to the 6, and you get 6 minutes and 29 seconds.

(2a+b)^2 how do you do this
gulaghasi [49]

•  Expand (2a + b)²:

(2a + b)²

= (2a + b) · (2a + b)


Multiply out the brackets by applying the distributive property of multiplication:

= (2a + b) · 2a + (2a + b) · b

= 2a · 2a + b · 2a + 2a · b + b · b

= 2²a² + 2ab + 2ab + b²


Now, group like terms together, and you get

= 2²a² + 4ab + b²

= 4a² + 4ab + b²    <———    expanded form  (this is the answer).


I hope this helps. =)
