The answer would be 56n^2 + 19n - 15
Multiply 8n with 7n to get 56n^2, then multiple 8n with 5 and you get 40n, then multiple -3 with 7n to get -21n, then -3 times 5 which gives you -15. Simplify and that is the answer you would get.
Answer:
rate of change=slope= y2-y1/x2-x1
Step-by-step explanation:
x: -2|-1|0|1
y : 5|4|3|2
so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)
now we plug them in: 
4-5=-1
-1-(-2)=1
so -1/1 is equal to -1, meaning it's answer option b.
A is not true, there are only 1 in the 70 inches tall column, and 3 in 69 1/2 column.
B is right, there are more dots in the right side of the data set.
C is not true, there is one dots in the 68 1/2, which means there is one player that is 68 1/2 inches.
D is right, because there are four dots in the column of 71
E is right, because there are total 6 different list/ column of dots.
F I am not sure, I think it is not true, because 74 inches is more like a outlier than 68 1/2
Right answer: B D E
