Question

What value goes in box A?

Answer 1

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 = $2x^{2}$

Box D 3 and x intersect

3 * x = 3x

To solve this we put all these together

$2x^{2} +3x+8x+12$

Combine like terms

$2x^{2} +11x+12$

Hope this helps!
