Option C: (x+4) and (x-1) are the factors of the equation
Explanation:
Given that the equation is
We need to determine the factors of the equation.
Splitting the middle term, we get,
Grouping the terms, we have,
Let us factor out the term (x+4), we have,
Thus, the factors of the equation are (x+4) and (x-1)
Hence, Option C is the correct answer.
Answer:
The cost of plastering the four wall at the rate of Rs 20 per meter square is Rs 3,543.4
Step-by-step explanation:
Given as :
The cost of carpeting a room = Rs 64,000
The rate of carpeting = Rs 540 m²
The breadth is twice its height
The length is twice its breadth
Let The length = L m
The breadth = B m
The height = L m
So, according to question
L = 2 B and B = 2 H
Now, Area of rectangular carpet = Length × Breadth
Or, A = L × B
Or, A = 2 B × B
∵ The cost of carpeting at the rate of Rs 540 per m² = Rs 64,000
So, area =
Or, 2× B² = 118.518
Or, B² =
Or, B² = 59.259
I,.e B = = 7.69 m
The length = 2 B
I.e L = 2 × 7.69 = 15.38 m
and H =
I.e H = = 3.84 m
So, Length = 15.38 m , Breadth = 7.69 m , height = 3.84 m
∵ The area of four wall = 2× ( Length + Breadth ) × height
or, The area of four wall = 2× ( 15.38 + 7.69 ) × 3.84
Or, The area of four wall = 177.17 m²
Now The rate of plastering the four wall = Rs 20 per square meter
So, The cost of plastering the four wall = area of four wall × rs 20
∴ The cost of plastering the four wall = 177.17 × Rs 20
I.e The cost of plastering the four wall = Rs 3,543.4
Hence The cost of plastering the four wall at the rate of Rs 20 per meter square is Rs 3,543.4 answer
