In order to simplify the expression (b+11)2b, we need to use the concept of distributive property.
Distributive property:
The distributive property of multiplication over addition can be used when you multiply a number by a sum.
Our expression is:
2b(b+11)
Applying distributive property here :
Answer: 
Divide both length and width by the dialtion factor and that will be the dimensions of the new rectangle. 2.5714in by 3.4286in. Round as needed
The quadratic function that models the data given in the table is 203.8x² - 26.6x + 8.6
<h3>What is the quadratic function?</h3>
A quadratic function is an equation that usually has a single variable and it is raised to the power of 2.
A quadratic function has the form : ax² + bx + c = 0
Where: a, b,c are known numbers and x is unknown
Given the quadratic function: 185x²+ 1.
- Number of views when 1 day has passed = 185(1) + 1 = 186
- Number of views when 6 days has passed = 185(6²) + 1 = 6661
Given the quadratic function: 203.8x² - 26.6x + 8.6
- Number of views when 1 day has passed = 203.8(1)² - 26.6(1)+ 8.6 = 185.80
- Number of views when 6 days has passed = 203.8(6)² - 26.6(6) + 8.6 = 7185.80
