Six equals x is the answer.

6

8

x = 12

The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)

x = 2y = 4

Answer: x = 8/7

(3, 2)

x=1.6225

x-2+4=-8 x+2=-8 x=-10

6 + 2 = 8Therefore x = 6.

x =2 so 2 +6=8

(8,-8)

(1 + 8)*(8 + 2) = 90

The values are: x = -6 and y = 10

9 plus 7 equals 144. Generally, x plus y = x(x+y).

5x+2=x+10 5x-x=10-2 4x=8 x=2

8-5(2+x)=2(x+1)

X = 8

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.

x= -5

x+8=10 x=10-8 (I transposed it!) x=2
