Answer:
Note that I slightly misread the question and in the steps below found the answer to the nearest thousandth. To the nearest hundredth though, the rectangle has a length of 6.69cm, and a width of 1.35 cm.
Step-by-step explanation:
We are told that the rectangle has an area of nine square centimetres, and that it's length is 4 centimetres more than twice its width. We can express those as:
and
We also know that the area of a rectangle is its length times its width:
We can take that last expression, and plug in the other two, to solve for w
We can then plug that into expression "l = 2w + 4" to find the length:
Now let's see if we have that right, we can multiply these and see if we get an area of 9:
Which after accounting for rounding errors is matches the 9 square centimetres.
9y is the answer I believe
Answer:
Don't have an answer but I will explain what to do.
Step-by-step explanation
You're going to mark the point's on your graph paper, then make a right triangle, after that you're going to count over how many square's there are until you run to the end of the right triangle and also do that for both sides. After you found out what the number is you are going to multiply that number by it for both of them. Then after you found that out your going to take your calculator and press 2nd and X2 and put your number after that. Hope this helps!
Answer:
1.6
Step-by-step explanation:
becuase 0.1 times 16 it will be 1.6
(0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1+0.1 =1.6)
