We need to look at factors of 2, which are only 2 and 1... How do we get them to add to -3? Well, they have to be negative.
-2 + -1 = -3
What about the multiplication? A negative × a negative = a positive, so
-2 × -1 = 2
So your answer is
-2 and -1
2 because it is when you round 3/4 to 1 and 18/19 to 1. you then add 1+1 equals 2 . so my answer is correct.
So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is
, with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12: 
y = 4x^2 + 8x + 3: 
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
Answer: 26
Step-by-step explanation:
cut 3 and 15
cut 5/10 which was 15/10
15/10=2
then multiply 13*2 = 26
Find the area of all the sides and then divide each area by two. add them all up to get your answer.
