(3x - 7)(2x + 9) = 0 x = 7/3 or -9/2
x2-13x+36=(x-9)(x-4)=0 x=9 or x=4
Y+7=9 equals 2+7=9.
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
144 9+7 = 16 and 9*16 = 144
(3x - 7)(2x + 9) = 0 x = 7/3 or -9/2
7x + 7 + 6x - 9 = 13x - 2
x2 + 13x + 36 = 0 so (x+4)(x+9) = 0 so that x = -4 or x = -9
x2-13x+36=(x-9)(x-4)=0 x=9 or x=4
17x + 9
96
If I am correct, 9 plus 7 equals 112.
Y+7=9 equals 2+7=9.
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
144 9+7 = 16 and 9*16 = 144
It is: -2+9 = 7
x2 + 13x + 36 = (x + 9)(x + 4)
