Very simple
? – (20 – 4x – 5x2) = 20 – 7x2, so ? = 20 – 7x2 <span>+ (20 – 4x – 5x2)
</span>? = 20 – 7x2 <span>+ (20 – 4x – 5x2)=20-7x²+20-4x-5x²=40-12x²-4x
</span>the answer is <span>C. 40-4x-12x^2</span>
Answer:
23.4 units
Step-by-step explanation:
Given the point of the vertices of triangle ABC as A(−5,1), B(2,1), and C(6,4).
The distance (d) between two points X (x₁ , y₁) and Y(x₂, y₂) is given as:
. We can use this to calculate the length of the sides of the triangle. Therefore:

The perimeter of the triangle ABC = AB + AC + BC = 7 + 11.4 + 5 = 23.4 units
