Answer:
Option A for part A and $79 for part B
Step-by-step explanation:
We're going to solve each of the systems to determine the solution.
<u>System </u>
using a graph tool
the solution is the line
see the attached figure N
<u>System </u>
using a graph tool
the solution is the shaded area
see the attached figure N
<u>System </u>
using a graph tool
The system has no solution
see the attached figure N
<u>System </u>
using a graph tool
the solution is the shaded area
see the attached figure N
therefore
<u>the answer is</u>
<u>System </u>
I hope this helps you
Area =3/4.5/12
Area =5/4.4
Area =5/16
52 quadrilaterals would have 52 ÷ 4 = a
a = your answer.
My answer is reasonable because if you have 52 sides from quadrilaterals you would need to divide by 4 to get the amount of quadrilaterals you have. Check your work by multiplying 4 x a = __ (The blank should be 52)
