Step-by-step explanation:
<u>Picture 1:</u>

First, add the 2x and x together for 3x
Then add 3 to both sides of the equation
Finally, divide each side by 3.
<u>Picture 2:</u>
<u />
<u />
First, add 7x and x together for 8x
Then, minus 20 from both sides of the equation
Finally, divide each side by 8.
( y - 4 ) ( y² + 4 y + 16 ) =
= y³ + 4 y² + 16 y - 4 y² - 16 y - 64 = y³ - 64
If the result is the polynomial of the form:
y³ + 4 y² + a y - 4 y² - a y - 64
a = 16
Answer:
i believe its 27
Step-by-step explanation:25 times two= 50 27 times two= 54 +one more is 55. so it is 27
