Simplify the expression:\newline(4+r)+3=(4 + r) + 3 = _____

Full solution

Q. Simplify the expression:\newline(4+r)+3=(4 + r) + 3 = _____
  1. Apply Associative Property: Apply the associative property of addition to simplify the expression.\newlineAssociative property: (a+b)+c=a+(b+c)(a + b) + c = a + (b + c)\newline(4+r)+3=4+(r+3)(4 + r) + 3 = 4 + (r + 3)
  2. Simplify Expression: Simplify the expression by adding the constants. 4+(r+3)=4+r+34 + (r + 3) = 4 + r + 3
  3. Combine Constants: Combine the constants.\newline4+r+3=4+3+r4 + r + 3 = 4 + 3 + r
  4. Add Constants Together: Add the constants together. 4+3+r=7+r4 + 3 + r = 7 + r
