The number in the question that gives 28 after the operations is; <em><u>3</u></em>
We are told that the product of seven and the sum of a number and 1 is 28.
Let the number be x. Thus;
7(x + 1) = 28
Use division property of equality to divide both sides by 7.
7(x + 1)/7 = 28/7
(x + 1) = 4
Use subtraction property of equality to subtract 1 from both sides to get;
x + 1 - 1 = 4 - 1
x = 3
Therefore, in conclusion the number is 3.

Answer:
\frac{\left(5x+1\right)\left(3x+1\right)}{2x-y}
Step-by-step explanation:
15x^2+8x+1:\quad \left(5x+1\right)\left(3x+1\right)
add on 2x -y as the denominator of the fraction
A: 100m^2
10 x 10 = 100
B: 28.274m^2
You have to do pi x r squared
So,,,
Pi x 3^2
9pi = 28.274....
C: just subtract the grass bed from the land...
100 - 28.274 = 71.72566612...
So C is 71.726m^2
Hope this helped! Have a nice day :)
