A rectangular pool is 25 feet long and 12 feet wide. If the length is increased by 2x what is the new length?
Let's work on this together! It's really easy, assuming you didn't make a typo.
ok
Alright, so tell me two things: What was the original length How much did they say we're increasing it by?
25 and it only said it increased by 2x
the orginal equation is A rectangular pool is 25 feet long and 12 feet wide. If the length is increased by 2x what is the new length? If the width is decreased by x, what is the new width?
Excellent! So how do we show when something gets increased by something else? Do we add/subtract/divide/multiply? For example: I had 3 apples. I increased the number of apples by 2.
add
Excellent! So the length is now 25 + 2x So you tell me what the width is.
12 - x
Whoops! You're right. It's -. I misread it. Great work!
thanks
No problem!
so what next
what so we do next
i mean so what do we do next
That's all. If the question asked for what the new length/width are, that's all you need. Unless.... they gave you more information (like what x =) or what the area/perimeter is. But like I said, if you didn't make any typoes, that is your answer.
ok
