Since neither of the bracketed expressions is preceded by a minus sign, and neither one has a multiplier outside of it, all of the parentheses can simply be removed.
<span>(3x - 5) + (3x + 6)
3x - 5 + 3x + 6
Combine the 'x'-terms: 3x + 3x = 6x
Combine the numbers: -5 + 6 = 1
The expression is equivalent to . . . . . <u>6x + 1</u>

Answer:
Volume of the piece in the picture = 350 cubic inches
Volume of the remaining piece = 300 cubic inches
Step-by-step explanation:
Given question is incomplete without the picture; here is the picture as an attachment.
Volume of the rectangular prism = Length × width × height
V = 5 × 13 × 10
= 650 cubic inches
Now volume of the piece given in the picture = Volume of prism at the base + Volume of the prism with triangular base
= 10×5×1 + 
= 50 + 
= 50 + 300
= 350 cubic inches
Volume of the other piece = 650 - 350
= 300 cubic inches
