Answer:
Third option: 12x^2+8x+25
Step-by-step explanation:
s1=8x^2
s2=4x^2+15
s3=8x+10
Total perimeter of the pool edge: P
P=s1+s2+s3
Replacing s1, s2 and s3 in the formula above:
P=(8x^2)+(4x^2+15)+(8x+10)
P=8x^2+4x^2+15+8x+10
Adding like terms:
P=12x^2+8x+25
- <u>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</u>
- <u>Convert the problem to an equation using the percentage formula: P% * X = Y.</u>
- <u>P is 10%, X is 150, so the equation is 10% * 150 = Y.</u>
- <u>Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.</u>
- <u>Multiply by 100 and add a percentage </u><u>sign</u>
- <u>0.876 = 0.876 * 100 = 87.6%</u>

The easiest way to find the vertex is to convert this standard form equation into vertex form, which is y = a(x - h)^2 + k.
Firstly, put x^2 - 10x into parentheses: y = (x^2 - 10x) + 30
Next, we want to make what's inside the parentheses a perfect square. To do that, we need to divide the x coefficient by 2 and square it. In this case, the result is 25. Add 25 inside the parentheses and subtract 25 outside of the parentheses: y = (x^2 - 10x + 25) + 30 - 25
Next, factor what's inside the parentheses and combine like terms outside of the parentheses, and your vertex form is: y = (x - 5)^2 + 5.
Now going back to the formula of the vertex form, y = a(x - h)^2 + k, the vertex is (h,k). Using our vertex equation, we can see that the vertex is (5,5).
Answer:
y=1/1

Answer:
−8 < x < 2 would be the answer if the equation was x^2
if the equation was x(2), the answer is x<2
