Can someone help me with this?<br> (5+w)(w+4)
mel-nik [20]

Answer:

<u>w^2+9w+20</u>

Step-by-step explanation:

Apply the FOIL METHOD: (a + b) (c + d) = ac + ad + bc + bd

a = 5        

b = w        

c = w            

d = 4

= 5w + 5 x 4 + ww + w x 4

= 5w + 5 x 4 + ww + 4w

Simplify 5w + 5 x 4 + ww + 4w:

<u>w^2 + 9w + 20</u>
