Answer:
y > 
Step-by-step explanation:
Given
5y + 3 > - 7y + 13 ( add 7y to both sides )
12y + 3 > 13 ( subtract 3 from both sides )
12y > 10 ( divide both sides by 12 )
y > 
, that is
y >
Answer:
-6x-42
Step-by-step explanation:
Open parenthesis.
-42-6x is what you get once opened.
I'm not sure if you're already given the length of the rectangle, but the width is either (x + 3) or (x + 15).
We can find this by factoring x² + 18x + 45, as the area of a rectangle is found by multiplying the length and width together, so if we factor this expression we can find what was multiplied together.
Factoring x² + 18x + 45, we get (x + 3)(x + 15), which then tells us the two sides of the rectangle. Again, I'm not sure if you were already told the length, but if you were then the width is the other side. For example, if you were told the length was (x + 3), then the width would be (x + 15).
I hope this helps!
