If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
x = 8, y = 5
13 less than 4 times a number 13 less than is "-13" 4 times a number is "4x" 4x-13■
if the number is the same: 2x + 3x = 13 5x = 13 x= 13/5
It is: 1 times 13 = 13 which is a prime number
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
(-8,1)
x = 8, y = 5
No. A square number is the product of a number multiplied by itself. Nine (3 times 3) and 16(4 times 4) are the two square numbers closest to 13.
13 less than 4 times a number 13 less than is "-13" 4 times a number is "4x" 4x-13■
x + y = 13 . . . . . . . . . . (A)2*x + 3*y = 1 . . . . . . . (B) (B) - 2*(A) : y = -25 Then, by (A) x - 25 = 13 so that x = 38.
if the number is the same: 2x + 3x = 13 5x = 13 x= 13/5
How about 9 times 13 = 117 as one example
A number is divisible by 13 if it is a multiple of 13. In other words, 13 times a number results in a big number that is divisible by 13.
The 13th square number is simply 13 times 13 = 169
168
The square of 13 is 13 times 13 or 169.
