Add the whole numbers since they all have the square root of 6: 4+2-1=5. The answer is 5squre root of 6 or D :)
89=x+1/3(7)
89=x+7/3
267/3=x+7/3
260/3=x
86 2/3=x. Hope it help!
Answer:
I’m very unsure but I think it is b
Step-by-step explanation:
Let's call the width
. Since the length is three more than the width, it is
.
The area (which we know to be 70) is given by the multiplication of width and length:

To solve this equation, you can use the usual quadratic formula: given an equation
, the two solutions are

which in your case becomes

So, two solutions are

Since we can't accept a negative length, we only accept the second solution.
So, the dimensions are 7 and 10
All divisions by powers of ten entail moving the decimal point left by the number of zeroes. So 31.5/10 = 3.15.
