Answer:
-2x -8
Step-by-step explanation:
The border area will be the difference between pool+border and pool. The area of each rectangle is the product of its dimensions.
(x+3)(x-2) -(x+2)(x+1) = (x^2 +x -6) -(x^2 +3x +2)
= x^2(1 -1) +x(1 -3) +(-6 -2)
= -2x -8 . . . area of border
Answer:
P(east) + P(west) = 0.12 + 0.18 = 0.3
So 0.3 is the correct answer.
Answer:
<h2>h = 4</h2>
Step-by-step explanation:
v = πr²h
To make h the subject divide both sides by πr²
So we have
when
π = 22/7
r = 7
v = 616
We have h as
<h3>h = 4</h3>
Hope this helps you
I think I know how to do it
Your equation is:
P₁V₁ = P₂V₂
You Know:
Initial:
P₁ = 84 Pa
V₁ = 336 L
New:
P₂ = ?
V₂ = 216L
Plug this into the equation:
P₁V₁ = P₂V₂
(84 Pa)(336 L) = P₂(216 L) Divide 216 on both sides
130.6666666 = P₂
(if your doing significant figures, you have 2 sig figs)
130 Pa = P₂
Mass divided by volume = density... I dont know the exact answer but i hope this helps
