Alex

7 is the missing numerator in the equivalent fraction with a denominator of 2.

<u>Step-by-step explanation</u>:

The mixed fraction is 3 1/2.

  • Convert it into a proper fraction to get a equivalent fraction.
  • Multiply the denominator 2 with 3 and then add 1 to the answer.

⇒ 3 1/2 = ((3\times2) + 1)/2

⇒ 3 1/2 =7/2

baherus [9]

Answer:

-5.6k-7

Step-by-step explanation:

you'd start by multiplying 6 by everything in the first pair of parentheses:

6(-2.1k-2)= (-12.6k-12)

then you'd add the like terms together:

(-12.6k-12)+(7k+5)= -5.6k-7

given that -4 is a zero of the function f(x)=x3+3x2-16x-48f(x)=x3+3x2-16x48, find the other zeros and write f(x)f(x) in factored
IrinaVladis [17]

Answer:

f(x) = (x + 4)(x - 4)(x + 3)

The other zeros of the function are at 4 and -3.

Step-by-step explanation:

Given function is f(x) = x³ + 3x² - 16x - 48.

Now, given that - 4 is a zero of the given function.

So, the function has a factor equals to (x + 4).  

Now, f(x) = x³ + 3x² - 16x - 48

⇒ f(x) = x³ + 4x² - x² - 4x - 12x - 48

⇒ f(x) = x²(x + 4) - x(x + 4) - 12(x + 4)

⇒ f(x) = (x + 4)(x² - x - 12)

⇒ f(x) = (x + 4)(x - 4)(x + 3)

Therefore, the other zeros of the function are at 4 and -3. (Answer)
