Multiply the two mixed numbers 4 1/2 x 3 2/3 simplify your answer and write it as a mixed number

Answer: 16 1/2

Step-by-step explanation:

It's easiest to multiply improper fractions and then to convert them back into mixed numbers, so 4 1/2 would become 9/2 and 3 2/3 would become 11/3. $\frac{9}{2} *\frac{11}{3}$ = 99/6. Now just simplify to 33/2 and then convert back into a mixed number. 16 1/2

Which is the better buy? Find the unit rate for each meat. Show your work and explain reasoning.

KATRIN_1 [288]

You start by changing the fraction into a decimal.

4.5 lb. of ground beef= 16.11

6.25 lb. of ground turkey= 18.50

Next, you divide the amount they cost by the pounds to get the price per pound.

16.11÷4.5= 3.58

18.50÷6.25= 2.96

So, a pound of beef is $3.58, and a pound of turkey is $2.96.

The turkey is 62 cents less than the beef per pound.

That means the turkey is a better buy! :)

(Have a good day! :))

Answer: A

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

f(x) = x³ + 4x² + 7x + 6

possible rational roots are ±{1, 2, 3, 6}

Try x = -2

-2 | 1 4 7 6

<u>| ↓ -2 -4 -6</u>

1 2 3 0 ← remainder is 0 so x = -2 is a root ⇒ (x + 2) = 0

The factored polynomial x² + 2x + 3 = 0 is not factorable so use the quadratic formula to find the roots.

a=1, b=2, c=3

$x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}$

$x=\dfrac{-(2)\pm\sqrt{(2)^2-4(1)(3)} }{2(1)}$

$x=\dfrac{-2\pm\sqrt{4-12} }{2}$

$x=\dfrac{-2\pm\sqrt{-8} }{2}$

$x=\dfrac{-2\pm2i\sqrt{2}}{2}$

$x = -1 \pm i\sqrt{2}$

$x = -1 + i\sqrt{2}$ $x = -1 - i\sqrt{2}$

$x - (-1 + i\sqrt{2})=0$ $x - (-1 - i\sqrt{2})=0$

The factors are:

$(x - 2)[x - (-1 + i\sqrt{2})][x - (-1 - i\sqrt{2})]$
