166, all you have to do is divide 4150 by 25
(y+x)^2=(x+y)^2
so
(x+y)^2+(x^2-2xy+y^2)
= (x^2+2xy+y^2)+(x^2-2xy+y^2)
= x^2+2xy+y^2+x^2-2xy+y^2
= x^2+x^2-2xy+2xy+y^2+y^2
= 2x^2+2y^2
if u want to simplify it more then it will be written as: 2(x^2+y^2)
Answer:
First choice.
Step-by-step explanation:
When you solve the system and somehow get both sides two different value. That means both graphs are oarallel (graph of both equations). When two sides are different, we can say that there are no solutions.
The formula for finding the surface area of a cube is A=6y^2 where y is the side length. we know a=96. so we just isolate y.
96/6= 6y^2 / 6
16=y^2
sqrt (16) = sqrt(y^2)
4=y
So y is 4
Answer:
The margin of error for the confidence interval is of 0.08 = 8%.
Step-by-step explanation:
A confidence interval has two bounds, an upper bound and a lower bound. The margin of error is half the subtraction between these two bounds.
In this question:
Lower bound: 0.5
Upper bound: 0.66
Margin of error: (0.66 - 0.5)/2 = 0.16/2 = 0.08
The margin of error for the confidence interval is of 0.08 = 8%.
