Answer:
l = 6 cm
w = 5 cm
Step-by-step explanation:
l(2l - 7) = 30
2l^2 - 7l - 30
(2l + 5)(l - 6)
l = 6
2(6) - 7 = 5
Answer:
3.5
Step-by-step explanation:
26, 31, 32, and 39
First we need to find the mean
(26+ 31+ 32+ 39) /4
128/4 = 32
The mean absolute deviation is sum of the positive difference between the number and the mean divided by the number of terms
((32-26)+ (32-31)+ (32-32)+ (39-32)) /4
14/4
3.5
