Part A: 5 is the coefficient, w is the variable, 50 is the constant
Part B: 10 x 5 = 50 + 2 x 20 = 40+ 50 = $140
Part C: the constant,50,would change and become 85. Hope this helps :)
Oooohhhhhhhhh Oooommmgggg Brooooo
Answer:

Step-by-step explanation:
<u>Equation of a circle</u>

(where (a, b) is the center and r is the radius)
Given:
- center = (5, 1)
- diameter = 4√5
Diameter = 2r (where r is the radius)
⇒ r = 4√5 ÷ 2 = 2√5
Substituting these values into the equation:


Answer:
30i + 6i^2
Step-by-step explanation:
we know that
A difference of squares problem can be factored as follows:

in this problem we have

Applying difference of squares
