Simplified: x^3+5x^2-2x+1
in standard form: x^3+5x^2-2x+1

P=Perimeter
L=Length
W=Width
Hints given are P= 76, L=20 so 2L=40
76=40+2w
76-40=2w
36=2w
18=w
Just input 3550 for (c) then for the second question input 24 for c times 50 +1900.
A). 33
B). 3100
Answer:
No, 20^2 + 21^2 ≠ 28^2
Step-by-step explanation:
3x3=9
