Answer:
108 dollars
Step-by-step explanation:
Cause first you have to find the unit rate of one lollipop which is 2 and then multiply that by a dozen which is 12 and you add that to the product of 3 times 24 which is 84 and 84 plus 24 gives you 108 and then you put the unit on it dollars so 108 dollars
Answer:
times 4 or multiply by 4each time
Answer:
The last choice.
Step-by-step explanation:
The last term is - 20 and because we have a coefficient of 1 on the x^3, and in order to get this last term and the given roots the factors have to be
(x + 5)(x + 4)(x - 1) so it is the last option.
The answer would be A) 5n + 16 because 5 is multiplying by n and +16 is adding 16 more .
Step-by-step explanation:
The first step in completing the square is to make the leading coefficient 1.
3 − 4x = 5x² − 14x
First, add 4x to both sides.
3 = 5x² − 10x
Divide both sides by 5.
3/5 = x² − 2x
The next step is to create the square. Take half of -2, square it, then add the result to both sides. (-2/2)² = 1.
3/5 + 1 = x² − 2x + 1
8/5 = x² − 2x + 1
Finally, factor the perfect square and solve for x.
8/5 = (x − 1)²
Take the square root of both sides.
±√(8/5) = x − 1
Add 1 to both sides.
x = 1 ± √(8/5)
