Answer: Rico is right.
(-1)(3x + 5)²
Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.
It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.
Then factor 9x² + 30x + 25 as
(3x + 5)²
Answer:
It’s A hope this is right good luck
Change in y over change in x
Answer:
And on this case we can use the product rule for a derivate given by:
Where 
and 
And replacing we have this:
Step-by-step explanation:
We assume that the function of interest is:
And on this case we can use the product rule for a derivate given by:
Where and
And replacing we have this:
Answer:
37.74 ft
Step-by-step explanation:
An angle and its opposite side are known
Sin (of the angle)= opposite/ hypotenuse
The hypotenuse is equal to the length of the ladder, therefore solve the hypotenuse
Sin (32)= 20/ hypotenuse
hypotenuse= 20/ Sin (32)
Sin (32)=0.5299
hypotenuse= 20/ 0.5299
37.74 ft
Hopefully this helps :)
