The answer yo your question is 33.6%.
Step-by-step explanation:
(f + g)(x)=
f×x + g×x =
fx + gx =
fx + gx= 3x² -x + 4 + 4x² - 5x + 2
3x² + 4x² -x - 5x + 4 + 2
=7x² - 6x + 7( I can't go past here)
Answer:
Statements 1, 3, and 5
Step-by-step explanation:
$480 = 12 days
To find daily sales, we want to figure out how much is made in 1 day. To do this, we can divide both sides by 12 to keep both sides equal but turn 12 days into 1. Thus, we have
$480/12 = 12/12 days
$40 = 1 day
We can go through the statements one by one.
1. $120 = 3 days
Does this match up with $40 = 1 day?
Multiply $40 = 1 day by 3 on both sides to compare the two dollar amounts. We get
$120 = 3 days.
The statements match up so this is correct
2. $240 = 7 days
Multiply $40 = 1 day by 7 on both sides
$280 = 7 days
This is false
3. $440 = 11 days
Multiply both sides of $40 = 1 day by 11
$440 = 11 days
This is correct
4. $500 = 13 days
Multiply both sides of $40 = 1 day by 13
$520 = 13 days
This is incorrect
5. $640 = 16 days
Multiply both sides of $40 = 1 day by 16
$640 = 16 days
This is correct
6. $960 = 22 days
Multiply both sides of $40 = 1 day by 22
$880 = 22 days
This is incorrect
