Evaluate the expression for x = 4: 6+ (10 - x)2 - 20

6 + (10 - 4)2 - 20 = 6 + 12 - 20 = 18 - 20 = -2

Assuming that the two in the middle of the expression is multiplied by (10 - x) the answer would be -2. I apologize if I did not read your question right.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
