Answer:
The answer is 27.25.
Step-by-step explanation:
Answer: the length is 24m
The width is 6 m
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of the given rectangle is 60 meters. This means that
2(L + W) = 60
Dividing through by 2, it becomes
L + W = 60 /2
L + W = 30 - - - - - - - - - - - - - -1
The rectangular room is 4 times as long as it is wide. This means that
L = 4W
Substituting L = 4W into equation 1, it becomes
4W + W = 30
5W = 30
W = 30/5
W = 6
L = 4 × 6
L = 24
Answer:
16. (4 + h)( 11 + h)
17. (2 - x)(20 - x)
18. (2 + x)(- 12 + x)
19. (6 + m)(- 7 + m)
20. x =4 and 3
21. x = 9 and -3
Step-by-step explanation:
16. 44 + 15h + h² = 44 + 11h + 4h + h² = (4 + h)( 11 + h) (Answer)
17. 40 - 22x + x² = 40 - 20x - 2x + x² = (2 - x)(20 - x) (Answer)
18. - 24 - 10x + x² = - 24 - 12x + 2x + x² = (2 + x)( - 12 + x) (Answer)
19. - 42 - m + m² = - 42 - 7m + 6m + m² = (6 + m)(- 7 + m) (Answer)
20. x² - 7x + 12 = 0
⇒ x² - 4x - 3x + 12 = 0
⇒ (x - 4)( x - 3) = 0
⇒ x =4 and 3 (Answer)
21. x² - 6x = 27
⇒ x² - 6x -27 = 0
⇒ x² - 9x + 3x - 27 = 0
⇒ (x - 9)( x + 3) = 0
⇒ x = 9 and -3 (Answer)
Given:
To find:
The equation that can be simplified to find the inverse of given equation.
Solution:
We have,
To find the inverse first we have to interchange x and y.
Now, we to solve this equation for y to find the inverse.
So, the equation can be simplified to find the inverse of given equation.
Therefore, the correct option is 4.
Answer:
40
