Answer:
36
Step-by-step explanation:
f(x)=x^2+2x+1
Let x = -7
f(-7)=(-7)^2+2*-7+1
= 49-14+1
= 36
Answer:
D. 4x + 2 = 46, 11 gallons
Step-by-step explanation:
First Part, Tank A = y , Tank B = x
y = 4x + 2
Second Part, Tank A = 46 so y = 46
46 = 4x + 2
44 = 4x
11 = x
Therefore, Tank B = 11 gallons
The interquartile range is 1.5
Q1 = 38 (between 34 and 43)
Median = 39
Q3 = 39.5 (between 39 and 40)
To get the interquartile range you find the difference with Q3 and Q1
39.5 - 38 = 1.5
