Answer:
x is less then or equal to -3
x<-3 (the < has to have a line underneath)
Step-by-step explanation:
Answer: width = 10 ft
Step-by-step explanation:
Area = length × width
Let l be length and w be width
l = w + 4 ........equation (1)
From above formula
140 = l × w. ........equation (2)
Substitute equation (1) into equation (2)
140 = (w+4) × w
w^2 + 4w= 140
w^2 + 4w - 140= 0
By factorization method
(w+14)(w-10)= 0
w=-14 or w= 10
So now width is 10 ft
From equation(1)
l=w+4
l= 10+4
l= 14 ft
Width = 10 ft and length = 14 ft
5x-40 if yo are trying to simplify it
Since the argument of the sine function is x without any scaling factor, the period is 2π, the 1st selection.
Answer:
a.) =30.72*50
b.)13.02*50
Step-by-step explanation:
you got to calculate the area of the two rooms by multipling the sides.
as we know that the scale is 1:50, this means for every 1meter it is 50 meters.
once we have calculated the area of the space used multply it by 50 to get the area dimensions occupied
