(5d + 5) - (d +1)
5 d + 5 - d - 1
4 d + 4
(5d + 5) - (d +1)
= 5d + 5 - d - 1
= 4d + 4
or
= 4(d+1)
to convince yourself pick some number for d, like 12
(60+5) - (12+1)
65 - 13
52
-----------------
now is that the same as
4(12) + 4 ????
48 + 4
52 sure enough
To simplify the expression (5d + 5) - (d + 1), we need to apply the distributive property and combine like terms.
Step 1: Distribute the negative sign to the terms inside the second parentheses:
(5d + 5) - (d + 1) = 5d + 5 - d - 1
Step 2: Combine like terms. In this case, the terms with 'd' and the constant terms:
5d - d = 4d
5 - 1 = 4
Thus, the simplified expression is 4d + 4.
