Answer:
90
Step-by-step explanation:
1. Start by making functions for the numbers
2. You can plug in these functions into a graph to figure out the x variable
- The intersection point of the two lines reveals the x and y
- The x would be your answer
3. To check if your x is right, plug it back into the two equations
- .89(90)+36=116.1
- 1.29(90)=116.1
The given polynomial is
→ 6 ac - 15 a d- 8 b c + 2 b d
→ 3× 2×a×c - 3×5×a×d - 2×2×2× b×c + 2×b×d
→ 3 a ( 2 c -5 d) - 2 b(4 c -d)
