Answer:
650 cm²
Step-by-step explanation:
Use the formula 2(lw+wh+lh)
Plug in the stuff: 2(5*9+9*20+5*20)=2(45+180+100)=2(325)=650 cm²
And there you go!

Answer:
E
Step-by-step explanation:
<u>Answer:</u>
The point-slope equation of the line is
or 
<u>Solution:
</u>
Let us assume that the slope is m and the y intercept of the line is b
Hence,
--------- (i)
y intercept means we need to find the value of y when x is 0
Here the line passes through point (4,-6) and slope m = (-2)
Now putting the point (4,-6) in equation (i) we get,





So, the equation of the line will be will be
or
