(D) 5x2 – x – 4

Your answer is D

Step-by-step explanation:

Here you go mate

Step 1

(2x^2-11x)+(3x^2 + 10x-4)  Equation/Question

Step 2

(2x^2-11x)+(3x^2+10x-4)  Simplify

(2x^2-11x)+(3x^2+10x-4)

Step 3

(2x^2-11x)+(3x^2 + 10x-4)  Combine terms

(2x^2+3x^2)+(-11x+10x)+(-4)

Step 4

(2x^2+3x^2)+(-11x+10x)+(-4)  Add

answer

5x^2-x-4

Hope this helps

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
