15 is 3 times 5. The point (5, 0) is dilated to the point (15, 0) by using a factor of
K = 3.
The average of 17 and 15 is 16 because if you add 17 and 15 together, and you divide them by 2, you get 16.
If it’s a negative slope A, if it’s a positive slope B
Answer:

Step-by-step explanation:
The given expression is
.
The technique that can be used to factor this polynomial is the difference of two squares.
We rewrite the two expressions as;

Recall that;



Answer:
w² +9w +20
Step-by-step explanation:
Multiply it out, collect terms, and write as descending powers of w.
(5+w)(w+4) = 5w +5·4 +w² +w·4
= w² +9w +20
