Answer:
12
Step-by-step explanation:
6 are striped which is half of them, the other half must be 6 then
6+6=12
7x+8(x+1/4) = 3(6x-9)-8
7x+8x+2 = 18x - 27 -24
15x + 2 = 18x - 51
+51 + 51
15x + 53 = 18x
-15x = -15x
53 = 3x
17.66 = x
Is this the image? If so, sorry I can't do this lol
Area is height time width, or in this case, 3(2x^2+3x+5), which is 6x^2+9x+15.
