1. Regroup terms
x(x+5)=104
2. Expand
x^2+5x=104
3. Move all terms to one side
x^2+5x-104=0
4. Factor x^2+5x-104
(x-8)(x+13)=0
5. Solve for x
x=8 or x=-13
Since x<0 is not possible in this case, x=8
6. Finding the dimensions
We know that one side has to be x+5, and now that we know x:
8+5=13
13*8=104
The dimensions are 13 and 8, have a nice day :D
Answer:
x^2+10x+25 is a polynomial
Step-by-step explanation:
A polynomial is an expression with exponets such as x^2 therefore your eqation that will become x^2+10x+25 is always a polynomial
Assuming you meant (x+5)^2
The volume of the small pool is the product of the cube of the scale factor and the volume of the large pool. 25.92 m cubed. Hope this helps.
Answer: 1/7
Step-by-step explanation:
Total questions answered = 49
Harry correct answers = 42
Harry wrong answers = (49 - 42) = 7
Thus, the only fraction of wrong answers = (Number of wrong answers / Total number of questions answered)
i.e 7/49
= 1/7
Thus, harry answered 1/7 of the 49 questions wrongly.
Greater than
1/6 x 3/2 = 1/4
1/4 > 1/6
