Step-by-step explanation:
Hello!
For this you multiply the numbers that intersect at that box
Box A 2x and 4 intersect
2x * 4 = 8x
Box B 3 and 4 intersect
3 * 4 = 12
Box C 2x and x intersect
2x * x = [tex]2x^{2}[/tex]
Box D 3 and x intersect
3 * x = 3x
To solve this we put all these together
[tex]2x^{2} +3x+8x+12[/tex]
Combine like terms
[tex]2x^{2} +11x+12[/tex]
Hope this helps!
