C. 2b and 2
This is because in order have like terms, they have to have the same properties. One of them (2b) has a variable next to it, while the other does not. This makes them not alike.
Hope this helps! :)
Hi there!
The question here is basically asking us to use ratios to find the length of the missing side. To do this, we must first construct a ratio. The best one would be -

Now, just cross multiply and solve for x.



Therefore, the length of the missing side would be
8. Hope this helped!
The approximate area will be 128.63 ( or 128.625 ) feet squared
Answer: y = 150 + 2.75x
Step-by-step explanation:
Since we are informed that the installation fee is $150.00 and that the tile is priced at $2.75 per square foot, x, the total cost, y, of the backsplash will be the addition of the fixed cost of $150.00 plus $2.75 multiplied by the number of square foot. This will be expressed as:
y = 150 + 2.75x
where,
x = number of square foot.
