Answer:
The intermediate step are;
1) Separate the constants from the terms in x² and x
2) Divide the equation by the coefficient of x²
3) Add the constants that makes the expression in x² and x a perfect square and factorize the expression
Step-by-step explanation:
The function given in the question is 6·x² + 48·x + 207 = 15
The intermediate steps in the to express the given function in the form (x + a)² = b are found as follows;
6·x² + 48·x + 207 = 15
We get
1) Subtract 207 from both sides gives 6·x² + 48·x = 15 - 207 = -192
6·x² + 48·x = -192
2) Dividing by 6 x² + 8·x = -32
3) Add the constant that completes the square to both sides
x² + 8·x + 16 = -32 +16 = -16
x² + 8·x + 16 = -16
4) Factorize (x + 4)² = -16
5) Compare (x + 4)² = -16 which is in the form (x + a)² = b
1 pound=16 ounches
3 times 16=48
48 ounces means 48 one ounce bags
The answer is -8°F. This is because it DROPPED 8 degrees, meaning it was 8°F MINUS 8°F which would equal 0°F. Hope that helps!
In standard form it would be 2,603,102. In expanded form it would be 2,000,000+600,000+3,000+100+2.
Answer: 945
Step-by-step explanation:
this month = 450.
next month 450x10/100=45, 450+45= 495
450+495= 945
