Answer:
32² = 1024
35² = 1225
71² = 5041
46² = 2116
Step-by-step explanation:
F(x) = x^4 + 81x^2
f(x) = x^2*x^2 + x^2*81
f(x) = x^2*(x^2 + 81) ... see note 1
f(x) = x^2*(x + 9i)(x - 9i) ... see note 2
note 1: if you haven't learned about complex or imaginary numbers yet, then you would stop at the line with "note 1" on it
note 2: you would stop here if you have learned about complex or imaginary numbers and you want to factor over the complex numbers. I used the rule that
a^2 + b^2 = (a+bi)*(a-bi)
For Perimeter you add all the sides of the figure and the total is your perimeter. For Area you multiply the length times the width.
The population of the study is club members who were asked whether they preferred a new sauna or new steam room
Answer:
x=5
Step-by-step explanation:
add 2 to both sides so then you have 4x=2x+10
then subtract 2x from both sides so you have 2x=10
then divide by 2 so you have x=5
