Give a direct proof of the lemma to Theorem 4.14. That is, given any rectangle with vertices (a, c), (b, c), (b, d) and (a, d), parameterize the boundary and verify directly that dz = zdz = 0.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

hi! i think the answer is 1/2 : )
