Answer:
3 4 6
Step-by-step explanation:
3/5
.60 is equal to 6/10
you can simplify that to 3/5
To calculate the number of shingles, we first calculate for the total area of the roof of Janice's house. From the figure, we can calculate the area of the two shapes: pyramid and a rectangular prism.
A(pyramid) = lw+l√[(w/2)²+h²]+w√[(l/2)²+h²]
A = 208 m²
A(prism) = 2(wl+hl+hw)
A = 293 m²
Total area = 501 m²
Number of shingles she needs = 501 m² / 2.25 m² =<span> 223</span><span>

Profit function is the difference between the revenue function, and the cost function
The polynomial that represents their share factor is given as:
<h3>Q1. The total profit</h3>
This means that we calculate P(10).
So, we have:
Hence, the total profit when x = 10 is (d) 675
<h3>Q2. The possible expressions</h3>
We have:
Factorize the above expression
Hence, the possible expressions for the individual shares are (b) 3x - 5 and 2x + 7
<h3>Q3. Equal shares</h3>
When their shares are equal, we have:
Collect like terms
Hence, the value of x when their shares are equal is (a) 12
<h3>Q4. The Sum of their shares</h3>
The sum of their shares is represented as:
Collect like terms
Hence, the sum of their shares is (b) 5x + 2
