Answer:
B c and d
Step-by-step explanation:
Answer:
The length and width are 11ft and 5ft respectively
Step-by-step explanation:
let the
length = L
Width = W
Area = LW = 55
The length is nine feet less than four times the width
L = 4W - 9
W (4W - 9) = 55
4W^2 - 9W -55 = 0
4W^2 - 20W + 11W - 55 = 0
4W(W - 5) + 11(W - 5) = 0
(W - 5)(4W + 11) = 0
W - 5 = 0 , 4W + 11=0
W = 5 or - 11/4
since the width cannot be negative, W = 5
LW = 55
L = 55/5
L = 11
The length and width are 11ft and 5ft respectively.
Answer: $36800
Step-by-step explanation:
Principal= $23000
Rate=6%
Time= 10years
Simple interest= Principal×Rate×Time / 100
= 23000×6×10 / 100
= 1380000/100
= $13800
Amount= Principal+Interest
= 23000+13800
= $36800
