Answer:
134
Step-by-step explanation:
1. seperate the rectangle bottom and the triangle top
2. I did the triangle first: 4×12=48÷2=24
3. the rectangle: 11×10=110
4. add the final numbers together: 110+24=134
2k^2+3k-13=k^2+15
subtract k^2 -15 from each side
k^2 +3k -28=0
(k+7)(k-4)=0
k=-7 k=4
Answer: k= -7,4
4x^2-5x-14 is your answer :)
