P = 2(L + W) ....this is the perimeter of a rectangle
P = 40
L = 5
40 = 2(5 + W)
40 = 10 + 2W
40 - 10 = 2W
30 = 2W
30/2 = W
15 = W <=== ur answer is 15 ft
Answer:y=1/6x
Step-by-step explanation:
Answer:
x≤-3 2 ≤x<7
Step-by-step explanation:
(x^2+x-6) /(x-7) ≤0
Factor the numerator
(x+3)(x-2) / (x-7)≤0
Critical points are
X =-3 X =2 X=7
We need to check the values when
x≤3 -3 ≤ x≤2 2 ≤x<7 x>7
(x cannot be 7 because then the denominator is zero)
and see when it is less than 0
Substitute a value in and see if factor is positive or negative
x≤-3
(negative)(negative) / (negative) = negative
-3 ≤x≤2
(positive)(negative) / (negative) = positive this range does not work
2 ≤x<7
(positive)(positive) / (negative) = negative
x>7
(positive)(positive) / (positive)
Step-by-step explanation:
Perimeter of the parallelogram =2(l+b)
Length =3x and Breadth = 2x
So,
2(3x+2x)=70cm
2*5x=70cm
5x=70 divided by 2,35
5x=35
x= 35 divided by 5, 7
X=7cm.
Length =3x=3*7=21cm
Breadth =2x=2*7=14cm
