Problem Understanding: Understand the problem. We need to calculate the sum of the expression (x+5) for each integer value of x starting from 0 up to 2.Step 1: Calculate sum for x=0: Calculate the sum for x=0. Substitute x with 0 in the expression (x+5). Sum for x=0: (0+5) = 5Step 2: Calculate sum for x=1: Calculate the sum for x=1. Substitute x with 1 in the expression (x+5). Sum for x=1: (1+5) = 6Step 3: Calculate sum for x=2: Calculate the sum for x=2. Substitute x with 2 in the expression (x+5). Sum for x=2: (2+5) = 7Step 4: Add the sums: Add the sums from steps 2, 3, and 4. Total sum: 5 + 6 + 7 Total sum: 18

\sum_{x=0}^{2}(x+5)=

Problem Understanding: Understand the problem. $\newline$ We need to calculate the sum of the expression $(x+5)$ for each integer value of $x$ starting from $0$ up to $2$ .
Step $1$ : Calculate sum for $x=0$ : Calculate the sum for $x=0$ . Substitute $x$ with $0$ in the expression $(x+5)$ . Sum for $x=0$ : $(0+5) = 5$
Step $2$ : Calculate sum for $x=1$ : Calculate the sum for $x=1$ . Substitute $x$ with $1$ in the expression $(x+5)$ . Sum for $x=1$ : $(1+5) = 6$
Step $3$ : Calculate sum for $x=2$ : Calculate the sum for $x=2$ . Substitute $x$ with $2$ in the expression $(x+5)$ . Sum for $x=2$ : $(2+5) = 7$
Step $4$ : Add the sums: Add the sums from steps $2$ , $3$ , and $4$ . $\newline$ Total sum: $5 + 6 + 7$ $\newline$ Total sum: $18$
