Answer:
$492 per year
Step-by-step explanation:
The first step we take towards solving this question is to add all the numbers we were given as money spent(excluding that of the month)
$20 + $10 + $18 + $3 = $41 per month
This means that a total of $41 was spent per month.
Going further, since we're told it's 12 months, we then multiply it by 12, and thus, we have
$41 * 12 = $492 per year
Therefore, the total money spent is $492 per 12 months, or per year

Answer:
320x^2+140x-10
Step-by-step explanation:
(16x-1)(20x+10)
320x^2+160x-20x-10
320x^2+140x-10
If you factor the trinomial using the AC method the answer would be
(x-3)(x+9)
