Because we're treating the swimming pool as a standard rectangle, rather than a three dimensional shape, we can use the formula L * W = A to calculate the length of the pool.
Length * Width = Area
We've established two key bits of information, and with them we can solve for the final piece.
Length * 4 = 16
4l = 16
Divide both sides by 4.
l = 4
<h3>The length of the pool is 4 meters.</h3>
C. 8k+17
in your expression you have:
(7k-4k+5k)+(13+10-6)=
=(8k)+(17)

Answer:
x=90
y=67
Step-by-step explanation:
as the line that bisects the vertical angle of isosceles triangle perpendicularly bisects the base
so x=90
and sum of all sides of triangle is 180 so
90+23+y=180
therefore,y=67
5. y = x + 7
6. y = -x + 1
