= ( 3x² + 3x + 5 ) ( 6x + 4 )
= 18x³ + 18x² + 30x + 12x² + 12x + 20
= 18x³ + 30x² + 42x + 20
Yes the answer would be B
a) (2a - b)² = (4a² - 4ab + b²)
b) (10m - n²)² = (100m² - 20mn² + n⁴)
c) (4x - 4²) = (16x² - 8x + 4⁴)
d)
e)

f)

<h3><u>
The value of the number is equal to 16.</u></h3>
7x + 8 = 120
<em><u>Subtract 8 from both sides.</u></em>
7x = 112
<em><u>Divide both sides by 7.</u></em>
x = 16
