4 because doubled it equals eight, add four it equals twelve, subtract four it equals eight, subtract three and it equals five.
Answer:
D. (-2,1)
Step-by-step explanation:
we have

This is the equation of a vertical parabola open upward The vertex represent a maximum
Convert the quadratic equation in vertex form

where
(h,k) is the vertex
Complete the square



Rewrite as perfect squares

The vertex is the point (-2,1)
Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.
7. 2x+6x+8 = 32
8x+8=32
-8 -8
8x=24
— —
8 8
X=3
5. 34 because 4 and 2 are the same angle
3. 2x+24=146 is x=61
4.symetric property
6. 4 is 110 since it is equal to two and 1 is 70 since 180 - 110 is 70 and 3 is equal to 1
1.refective property
2. 2y/5
