Hii I believe your option would be D. I hope it helps :)
Answer:
90°
Step-by-step explanation:
Given - Mariyam wants to cut her chocolate brownie into two rectangles.
To find - What kind of angles will Mariyam form?
Proof -
If she cut the brownie in the rectangular shape, then the angle formed is 90°.
Y = -x2 + 5x + 36 <span>→ y = -(x2 -5x -36)
</span><span>→ y = -(x2 - 9x +4x - 36)
</span><span>→ y = -[x(x-9) + 4(x - 9)]
</span><span>→ y = -(x - 9)(x + 4)
Your answer would be </span>y=-(x-9)(x+4).
Symbolically, write this:
C
7 5. Know how to evaluate that?
C stands for "combination."
The answer is x = 6
hope this helps
