Grade: 6-b Lesson: S4-L4

Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Steps	Problem	Solution
1	Determine the value of an expression by substituting the values r = 4,s = 0,t = 9	\$ (r+s+t)^2 \$
2	Now substitute "r,s,t" values in the expression	\$ (4 + 0 + 9)^2 \$
3	After simplification we get	\$ (13)^2 \$
4	After simplification we get	\$ 169 \$
5	Answer	B = \$ 169 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the values
r = 4,s = 0,t = 9

\$ (r+s+t)^2 \$

Now substitute "r,s,t" values in the expression

\$ (4 + 0 + 9)^2 \$

After simplification we get

\$ (13)^2 \$

After simplification we get

\$ 169 \$

Answer

B = \$ 169 \$
