Answer:
71
Step-by-step explanation:
Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd
71
We do not need to look at all differences.
We need to find two numbers fairly far appart,
and not all look promising.
You could look at approximate differences,
or you could look at the last digit.
71-35 and 63-17 are the only promising differences,
because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,
and when you calculate the last digit you calculate
11-5=6 and 13-7=6.
71-35=36
Since it’s supplementary the straight line would equal to 180 degrees
4d - 1 + 105 = 180
4d + 104 = 180
4d = 76
d = 19
Answer:
3x - 2.
Step-by-step explanation:
The length = area / width.
The area 3x^2 + 7x - 6 = (3x - 2 )(x + 3)
so the length = (3x - 2 )(x + 3 ) / x + 3
= 3x - 2.
Answer:
![A_{white} = 119\ cm^2](https://tex.z-dn.net/?f=A_%7Bwhite%7D%20%3D%20119%5C%20cm%5E2)
Step-by-step explanation:
<u>Step 1: Determine the area of the black area</u>
![A = l * w](https://tex.z-dn.net/?f=A%20%3D%20l%20%2A%20w)
![A = 8\ cm * 2\ cm](https://tex.z-dn.net/?f=A%20%3D%208%5C%20cm%20%2A%202%5C%20cm)
![A = 16\ cm^2](https://tex.z-dn.net/?f=A%20%3D%2016%5C%20cm%5E2)
<u>Step 2: Determine the area of the entire white and black area</u>
![A = l * w](https://tex.z-dn.net/?f=A%20%3D%20l%20%2A%20w)
![A = 9\ cm * 15\ cm](https://tex.z-dn.net/?f=A%20%3D%209%5C%20cm%20%2A%2015%5C%20cm)
![A = 135\ cm^2](https://tex.z-dn.net/?f=A%20%3D%20135%5C%20cm%5E2)
<u>Step 3: Determine the difference to just get the white area</u>
![A_{white} = 135\ cm^2 - 16\ cm^2](https://tex.z-dn.net/?f=A_%7Bwhite%7D%20%3D%20135%5C%20cm%5E2%20-%2016%5C%20cm%5E2)
![A_{white} = 119\ cm^2](https://tex.z-dn.net/?f=A_%7Bwhite%7D%20%3D%20119%5C%20cm%5E2)
Answer: ![A_{white} = 119\ cm^2](https://tex.z-dn.net/?f=A_%7Bwhite%7D%20%3D%20119%5C%20cm%5E2)
