The answer is 4.
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
9 squared is another way of stating the equation 9 X 9, and 10 squared is another way of stating the equation 10 X 10. Find the answers to these equations, add them together, and you will have the answer.

x + 10
x + 5
5x-15x+10 = 10-10x when simplified Assuming a request to solve the equation: 5x -15x + 10 = 0 5x - 15x + 10 = 0 5x - 15x = -10 or (multiplying everything by -1 gives you -5x + 15x = 10) so 15x - 5x = 10 10x = 10 x =1
It is 36/6 +4 = 10
5x = sqrt(10) + 15x -10x = sqrt(10) x = -sqrt(10)/10 = -sqrt(10)
15x = -75, x = -5
It is equivalent to 15x+10
It is 16x squared plus 80x plus 100.Very complicated!
b= 10
109 = 9 + 100
16
10 plus 10 divided by 4 is 12.5
