L = 3 + 2w
Find the width
Area = 54
l × w = 54
(3 + 2w) × w = 54
3w + 2w^2 = 54
2w^2 + 3w - 54 = 0
(2w - 9)(w + 6) = 0
w = 9/2 or w = -6 (width shouldn't be negative)
w = 9/2
w = 4.5 m
Find the length
l = 3 + 2w
l = 3 + 2(4.5)
l = 3 + 9
l = 12 m
The width is 4.5 m, the length is 12 m
72 because I helped you show do you Andreas show me too
Answer:
$67,580.73
Step-by-step explanation:
$49,329÷100=$493.29 (1%)
$493.29×37=$18,251.73 (37%)
$49,329+$18,251.73=$67,580.73
Answer: -5°F
Step-by-step explanation:
The temp at noon was 3*F and in midnight the temp dropped 8*F. Therefore, the temp at midnight will be calculated as:
= 3°F - 8°F.
= -5°F
