Answer 1

Answer:

if x =7 then x + x =14

if x=10 then x+x = 20

if x=0 then x+x=0

if x=-3 then x+x=-6

if x=-8 then x+x=-8

Answer 2

Answer:

14, 20, 0, -6, -16

Step-by-step explanation:

x=7 : 7+7 =14

x=10: 10+10=20

x=0:0+0=0

x= -3: (-3)+(-3)= -6

x= -8:(-8)+(-8)= -16

here , x is real no.for x. equals to or greater than zero so answer is zero
