D. 48 mm squared

Hello!

To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.

Outer:

A = bh

A =  (12 · 5)

A =  (60)

A = 30 mm²

Inner:

A = bh

A = (4 · 3)

A = (12)

A = 6

30 - 6 = 24

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
