A=x²
Substitute x with 1 4/5 or 9/5
A=(9/5)²
A=(9/5(9/5)
A=81/25
A=3.24. As a result, area of the square is 3.24 square units. Hope it help!

Part A: Solve −np − 70 < 40 for n. Show your work. (4 points) Part B: Solve 4w − 7k = 28 for k. Show your work. (6 points
likoan [24]
For part A, lets write the problem

-np - 70\ \textless \  40
 
add 70 to both sides

-np - 70 + 70 \ \textless \  40 + 70

-np \ \textless \  110

we are going to reverse the inequality, to do this we are going to multiply both sides by -1

(-np ) ( -1 ) \ \textgreater \  110 ( -1 )

pn \ \textgreater \  -110

divide both sides by p

\frac{pn}{p}  \ \textgreater \  \frac{-110}{p}

our answer would be 

n \ \textgreater \    \frac{-110}{p}

lets go with part b, lets write the problem

4w - 7k = 28

subtract 4w from both sides

4w - 7k - 4w = 28 - 4w

-7k = 28 - 4w

divide both sides by -7

\frac{-7k}{-7}  =  \frac{28}{-7} - \frac{4w}{-7}

I few simplified it, we would be left with,

k =  -\frac{28 - 4w }{7}

I hope this helped!!

REPRESENT A PROBLEM: Six friends share 5 meat pies. Each friend first eats half of a meat pie. How much more meat pie does each
lord [1]
I cannot draw a picture, you can.

6 friends multiplied by 1/2 a pie each is 3 pies. That leaves 2 pies to divide evenly among 6 friends. 2/6 = 1/3. One third more pie more for everyone.
