Answer:
value of \(2d+3\) when d=8 is 19.
Step-by-step explanation:
Given the expression: \(2d+3\) ....[1]
Here, d is the variable.
when d = 8
Substitution property of equality states that:
if x =y then x can be substituted in y in any equation and y can be substituted in x.
Substitute d= 8 in [1] we have;
\(2(8)+3\)
⇒\(16+3\)
⇒19
Therefore, the value of \(2d+3\) when d=8 is 19
