A=LW and L=W+9 so
A=(W+9)W
A=W^2+9W
W^2+9W-A=0, since A=220
w^2+9w-220=0
w^2+20w-11w-220=0
w(w+20)-11(w+20)=0
(w-11)(w+20)=0
Since w>0
W=11 ft, and since L=W+9
L=20 ft
Answer:
360
Step-by-step explanation:
We need to find the LCM of 18,90 and 24.
The prime factorization of 18 = 2 × 3 × 3
The prime factorization of 90 = 2 × 5×3×3
The prime factorization of 24 = 2 × 3×2×2
LCM is least common multiple.
LCM = 2 x 2 x 2 x 3 x 3 x 5
= 360
Hence, the LCM of 18,90 and 24 is 360.
