Question

4.Find the value of x if the distance between two points (8 x) and (x 8) is 2sqrt(2) units.​

Answer 1

Step-by-step explanation:

(8-x)*2 +(x-8)*2 =2*2

64+x*2 -16x +64+x*2-16x =4

128+2x*2-32x=4

2x*2-32x +124=0

x*2-16x +62=0

Solve this

Answer 2

Answer:

(8-x)*2+(x+8)*2=2*2

64 +x*2-16x +64 +x*2-16x=4

128 +2x *2-32x=4

2x*2-32x+124=0

X*2-16x+62 =0

X=76
