well, p + (-2), now a sign in front of a grouping symbol usually means it has a 1*, so +(, really means +1*, thus p + (-2) really means p + 1*(-2), which gives us p - 2, and that'd be ordinally, 2 numbers to the left of "p".
likewise, 5 + p, is just the same as p + 5, so that value will be a number 5 numbers to the right of "p".
just as above, p + 1, is just one value to the right of "p".

sample space, the whole amount of 18, favorable outcomes 4 red hair ones.
4/18, which simplifies to 2/9 or about 0.22 or about 22%.
<u>ANSWER</u>
<u>EXPLANATION</u>
The given expression is
Recall that:
We use the law of exponents to get
Let us multiply in the exponents to get:
Recall again that:
This implies that:
We expand the power to get:
We multiply out to get:
Width: x
Length: 2x
Area=x(2x)=2x^2
2x^2=200
x^2=100
x=10 or -10(reject as x>0) [width cannot be less than 0, doesnt make sense]
Perimeter
=x+x+2x+2x
=6x
=6(10)
=60 yd
Thank you so much, you too.
