Answer:
g(x)= ((x+4)^2) -2
Step-by-step explanation:
...............
The formula is 180(n-2)= 1140 then you divide 1140 by 180 to get 8 so then it would like like n-2=8 add the 2 over and n (being the number of sides)= 10 so your answer will be 10
Answer:
Step-by The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.-step explanation:
FOIL
First = 6x(2x) = 12x
Outside = 6x(-3) = -18x
Inside = -5(2x) = -10x
Last = -5(-3) = 15
12x - 18x - 10x + 15
12x - 28 + 15
-16x + 15
Hope this helps =)
