Answer:
B.
Step-by-step explanation:
Area is width times height.
(5p-7)(3p+4)
Multiply using FOIL method
(First, outer, inner, last)
(5p*3p) + (5p*4) + (-7*3p) + (-7*4) =
15p² + 20p -21p - 28 =
15p²-p -28 =
B is the closest one. They might have made a typo.
Given function is f(x) = x³ -12x +16.
We can write it as x³ +0x² -12x +16.
We need to write the numbers in order from left to right, so it would be {1, 0, -12, 16}.
Given factor is x -2 = 0, that means x = 2. So we need to divide the numbers by 2.
So correct way to divide the function would be 2 L 1, 0, -12, 16.
Hence, option C is correct.
Answer:
s + 16 ≤ −80
Step-by-step explanation:
Analyze each part in the word equation:
"16 more than s" s increased by 16; s + 16
"is at most" is equal to or less than; ≤
"−80" -80
Put the equation back together:
s + 16 ≤ −80
Answer:
A $12.84
Step-by-step explanation:
Sweater was originally $48.00 before tax. $48.00 x 7% tax rate (.07) = $3.36 in tax
So the sweater originally would've cost $48.00 + $3.36 = $51.36
The sale price was 25% off the $48.00. $48.00 x 25% (.25) = $12.00
Then you subtract the $12.00 from the $48.00 to get the new price of $36.00
Now that's before tax, so $36.00 x 7% tax rate (.07) = $2.52 in tax
So the sweater would cost on sale $36.00 + $2.52 = $38.52
To figure out how much she would've saved you subtract the sale price & tax from the original price & tax $51.36 - $38.52 = $12.84
