You can use Guass Formula to find the sum from 1 through n .
(n+1)*n/2=141*140/2=141*70
Since we want to find the prime factors:
141=3*47
70=7*2*5
SO we need the greatest which is \(\left [ 47 \right ]\)
You could do complementary counting and see the ones that are not right.
1,2
1,3
2,1
And since the total ways are 25:
1(Because 25/25=1)-3/25(That are wrong)=22/25

Coefficent of x= x* a constant number or a constant number *x
So there is a x and 14.So we multiply and get 14x.There is a -23x and a 1 so we multiply and get
14x+(-23x).Which equals -9x.

The sum of the angles of the quadrilateral = 360 degrees ....
so
q + 4q+17 + 8q+21 + 15q+148 = 360
28q + 186 = 360
q = 6.214 Then the largest angle is 15 (6.214) + 148 = 241.2 degrees
We could do \(ab^4/ab^2=48/4\)
So the A will cancel out and we will be left with \(b^2=12\)
So the answer is \(2 \sqrt{3} \) or\(-2\sqrt{3}\)
So we can see that every number has at least one square divisor(except 0) which is 1.
Now we can see that it has to be 4 because it is divisble by 1^2 and 2^2
(x+7)^2=2x^2+x+1:Converting to base 10
x^2+49+14x=2x^2+x+1:Using the formula (a+b)^2 = a^2+b^2+2ab
x^2=13x+48
x=16
So the answer is 16
