Title: Determine the value of an expression by substituting the values

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 k = -10,l = 11,m = 8	\$ (k + l + m)^2 \$
2	Now substitute "k,l,m" values in the expression	\$ (-10 + 11 + 8)^2 \$
3	After simplification we get	\$ (-10 + 19)^2 \$
4	After simplification we get	\$ 9^2 \$
5	After simplification we get	\$ 81 \$
6	Answer	D = \$ 81 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the values
k = -10,l = 11,m = 8

\$ (k + l + m)^2 \$

Now substitute "k,l,m" values in the expression

\$ (-10 + 11 + 8)^2 \$

After simplification we get

\$ (-10 + 19)^2 \$

After simplification we get

\$ 9^2 \$

After simplification we get

\$ 81 \$

Answer

D = \$ 81 \$
