Given/equations formed from text:
I: l=w+3
II: A=l*w
III: new area B=(l-2)*w
IV: B=A-30
substitute l in II with I to remove l:
II': A=l*w=
(w+3)*w=
w^2+3w
substitute l in III with I to remove l:
III': B=(l-2)*w=
(w+3-2)*w=
(w+1)*w=
w^2+w
substitute A and B from II' and III' into IV:
B=A-30
w^2+w=w^2+3w-30
30=2w
w=15
insert w=15 into I:
l=15+3=18
->
A) dimensions of full size rectangle are width 15 and length 18
dimensions of reduced size rectangle are width 15 and length 16
B) full size: 15*18=10*18+5*18=180+90=270cm^2
reduced size: 15*16=10*16+5*16=160+80=240cm^2
Answer:
hey the answer is 204ft cubed (for some reason it doesn't let me insert the 3 power so i just wrote it as "cubed" if you dont know what that is its ^3)
Step-by-step explanation:
i just did 2*6*17 and got the answer. Mark brainliest and thank? Yeet! have an awesome day! :D
The common ratio is 3.
I hope this helps!
6:1 , basically asking the ratio of one to the other. Understand?
