Answer:
x = 20
Length = 20ft
Width = 12ft
Step-by-step explanation:
A = 240
x^2 - 8x = 240
x^2 - 8x - 240 = 0
x^2 - 20x + 12x - 240 = 0
x(x-20) + 12(x-20) = 0
(x+12)(x-20) = 0
x = 20
x = -12 (which we discard since x is a length)
So the dimensions are 20ft and 20-8 = 12ft
Answer:
a) 5:3
b) 7.5:5.3
Step-by-step explanation:
150min : 90min (1 and a half hour)

The factory makes 27 dresses.
<u>Step-by-step explanation</u>:
- It produces three dresses for every five shirts.
- Let x be the sets of five shirts produced.
- Therefore, x sets of three dresses are produced along with five shirts.
Total garments = number of shirts + number of dresses
⇒ 72 = 5x + 3x
⇒ 72 = 8x
⇒ x = 9
The number of dresses is 3x = 3(9) = 27 dresses.
