8x-7 plus 2x equals 6 plus 5x plus 2?
144 is the answer.2+3=10 which means 2+3=55*2=107+2=63 7+2=99*7=63now 9+7=? 9+7=1616*9=144
2 + 5 is 7 + 6 =13 + 7 = 20 + 8 = 28 + 9 = 37 + 10 is 47.
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.
1+2+3+4+5+6+7+8+9=37
7 + 5 + 4 ÷ 2 + 7 = 21
5 + 2 + 3 + 7 + (21/7) = 20
It is: 12+7+2 = 21
-2 + (-6) + 7 = -1
-16 + -2 + 7 = -11
2 + 12 + 7 = 21
Commutative property of addition. :)
The commutative property
No. 2 + 7 - 8 = 1 8 + 7 - 2 = 13
