The answer is vertex is (5/2, 27/2).
Find x= -b/2a where a=-2, b=10 then plug x value back into function to solve for y value of vertex (x,y).
Answer:
7,000,000,000
Step-by-step explanation:
since the closest number is less than 5 (1<5) you round down making the nearest billion 7
Not sure, but the areas of a triangle is BH/2 so the dimensions should be 8 and 6 then 10.
8 x 6 = 48
48/2 = 24
Maybe that can help with the equation
#4 is 47, 48, 49
47+48+49=144
