Answer:
121x2 + 36y2
Step-by-step explanation:
= (4x + 4)(x + 1)
= 4(x + 1)(x + 1)
= 4(x + 1)2 and is hence the fully factored form
not sure bout the rest though...... it may have mistakes in the question forms.
$440
notes $2 - n
notes $10 - m
n + m = 80 ----------> m = 80 - n
1 - 2/5 = 3/5
45 * $2 + 35 * $10 = 90 + 350 = $440
