1) 234+(y+749)=3091
2)8405+347+x)=8995

[] Answer(s) []

[] Explanation []

Problem 1: 234 + (Y + 749) = 3091

Remove Parenthesis:

234 + Y + 749 = 3091

Group Like terms:

Y + 234 + 749 = 3091

Add The Numbers: 234 + 749 = 983

Y + 983 = 3091

Subtract 983 From Both Sides:

Y + 983 - 983 = 3091 - 983

Simplify:

Y = 2108

---------------------------------------------

Problem 2: 8405 + (347 + X) = 8995

Remove Parenthesis:

8405 + 347 + X = 8995

Add Numbers: 8405 + 347 = 8752

X + 8752 = 8995

Subtract 8752 From Both Sides:

X + 8752 - 8752 = 8995 - 8752

Simplify:

X = 243

i believe the answer is the polygon, heptagon.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
