Answer
40
Work Step by Step
$(2 + d)^{2}$ - $3^{2}$
We are given that d = 5.
To evaluate this expression, plug in 5 for d in the original equation.
$(2 + 5)^{2}$ - $3^{2}$
According to the Order of Operations, first we must solve all operations inside grouping symbols like parentheses.
$(7)^{2}$ - $3^{2}$
Next, all powers must be simplified first before subtracting. Simplify the powers.
$(7)^{2}$ - $3^{2}$
$49 - 9$
Finally, subtract:
$49 - 9 = 40$
