Row 4
Explanation
Row 1 - 4+2+2+3+3 = 14 / 5 = 2.8
Row 2 - 3+3+4+3+2 = 15 / 5 = 3
Row 3 - 2+4+3+4+3 = 16 / 5 = 3.2
Row 4 - 3+4+4+7+3 = 21 / 5 = 4.2
Pythagoreon theorem
a^2+b^2=c^2
5^2+10^2=125 not 20^2
Answer:the answer is 4 that is truly The answer
-3(k+7)-5k+4=23
-3k-21-5k+4=23
Get rid of the numbers that aren't being multiplied by k:
-3k-5k=23+21-4
Add like things:
-8k=40
Divide by -8 on both sides to get k by itself and to make the equation even:
k=-5
Well, 1 foot has 12 inches. Since there is 4 feet you multiply 12 by 4. Which is 48. Once you have 48 inches you add the extra 8 inches. So you get 56 inches
Hope this Helps!
