Answer :
Expressions are mathematical statements without the equal sign
The value of 5w^2 - 5w - 8 when x = 3 is 22
How to determine the value of the expression
The expression is given as:
5w^2 - 5w - 8
When the value of w is 3, the expression becomes
[tex]5w^2 - 5w - 8 = 5*3^2 - 5*3 - 8[/tex]
Evaluate the exponents
[tex]5w^2 - 5w - 8 = 5*9 - 5*3 - 8[/tex]
Evaluate the products
[tex]5w^2 - 5w - 8 = 45- 15 - 8[/tex]
Evaluate the differences
[tex]5w^2 - 5w - 8 = 22[/tex]
Hence, the value of 5w^2 - 5w - 8 when x = 3 is 22
