Answer:
4(x-1/2)^2+0
Step-by-step explanation:
I used the formula (b/2)^2
If you are looking for 83 = x/9, then you must multiply 83 by 9 to get the numerator.
83 x 9 = 747.
If you are looking for x/83 = 9, then you must multiply 83 by 9 to get the numerator.
83 x 9 = 747.
Your missing whole number is 747.
Hope this helps!
The decimal form of 1/20 would be 5/100 which is 0.05
Answer:
840
Step-by-step explanation:
Hi there!
Usually, this kind of problem asks us the perimeter rather than the area. But when talking on this grid on how many cms are necessary to construct one made up of 9 squares 1cm x1 cm. We need to check one thing: Some line segments will be used twice. So this is not a classical perimeter question.
1) So we either manually and carefully count it avoiding not doing it twice the same common line segments.
Or.
2) By just applying an algorithm, Where n is the <em>nxn</em> grid

So, for the 20x20 grid
