Question

solve the inequality.
$-3(2 + d) \leq 15$
the solution is $square$.
graph the solution.

Explanation:

Step1: Expand left-hand side

$-3(2+d) = -6 - 3d$
Inequality becomes: $-6 - 3d \leq 15$

Step2: Add 6 to both sides

$-3d \leq 15 + 6$
$-3d \leq 21$

Step3: Divide by -3, flip inequality

$d \geq \frac{21}{-3}$
$d \geq -7$

Answer:

The solution is $d \geq -7$.

For the graph: Use the first option (closed dot pointing right), place a closed dot at $-7$ on the number line, and draw an arrow extending to the right.
