I don't like dividing polynomials so I'm going to set x=1 and try them out.
(1-2-14+3)/4 = -3
Of the choices, only D gives -3 when x=1
~~~~~~~~~~~~~~~~~~~~~~
That's as much test-taking as math. If we were to divide
x^2 - 5x + 1
-------------------------------
x + 3 | x^3 - 2x^2 - 14x + 3
x^3 + 3x^2
-5x^2 - 14x
5x^2 + 15x
x + 3
x + 3
More work, still choice D
For this case, the first thing we must do is define a variable.
We have then:
x: number of initial cards.
We write now the equation that represents the problem:
x - (4) * (6) = 54
From here, we clear the value of x:
x = (4) * (6) + 54
Rewriting:
x = 24 + 54
x = 78
Answer:
The number of cards that william has initially is 78. Lack of information to know how many cards his friends have.
General equation: a = k*b^2
Specifically: 10 = k*(3)^2 = 9 k
Solving for k: k = 10/9
Then a = (10/9)b^2. If b = 9, then a = (10/9)(9)^2 = 90 (answer)
Answer:
It would be 4
Step-by-step explanation:
Because 2 pounds is 32 ounces and she has 8 molds so you would divide 8 into 32 and get 4.
