The answer is 36t^2+4s^2
we cannot combine the t and s terms since they are differnet
we can only facotr
4(9t^2+s^2)
Circumference=2(pi)r or (pi)d
You know that Circumference=113.04
You know that the diameter=2x+4
Plug what you know into the equation and solve for x.
C =(pi) d
113.04=(pi)(2x+4)
<span>4a+7b+3a-2b+2a
Substitute all of the variables for the numbers given
4(-5)+7(3)+3(-5)-2(3)+2(-5)
Multiply all of the variables by their coefficient
-20+21-15-6-10
Combine like terms
Final Answer: -30
