The answer for number 4 is scooter
Answer:
the correct answer is below
Step-by-step explanation:
11p7-9p5+8p³-4p7+13p5-5p³
11p7-4p7-9p5+13p5+8p³-5p3
=7p7+4p5+3p³
note: I multiply all the terms in the second parentheses by the negative sign that is beside it.
Area=side^2
if we say area=y and side=x
y=x^2
an euation is linear if the highest power of the variables is 1
y^1=x^2
2≠1
it is not linear (it's quadratic, fancy term for 2nd degree)
The center is at (0,0) so the equation will be like
x^2 + y^2 = r^2 where r = radius of the circle.
from the diagram you can see that r = 4
answer is x^2 + y^2 = 16
Since it is 10 less and you are trying to find out your number, you add 10.
71+10= 81
So, your number is 81.
