Beth made wristbands and belts for a craft sale. She sold 30 of these items. Each wristband sold for $5.50. Each belt sold at $8

baherus [9]

<u>✿</u><u>Answer:</u>

Both sold 18 wristbands and 12 belts

✂----------------------

Let, number of wristbands = x

number of belts = y

$x+y=30$ ➞ $x~5.5$

$5.50x+8.75y=204$ $x1$

$5.50x+5.5y=165\\5.5x+8.75y=204\\---------\\-3.25y=-39$

$y=-39/3.25$

$y=12$

$x=30-12=18$

$So, Both~ sold ~18 ~wristbands ~and ~12~ belts$ .

The factorization below is missing two positive integers a and b. 6x^(3)+18x^(2)-240x=6x(x-a)(x+b) Factor the polynomial and the

Dvinal [7]

Answer:

a = 5

Step-by-step explanation:

Hello, please consider the following.

$6x^3+18x^2-240x=6x(x^2+3x-40)\\\\\text{** The sum of the zeroes is -3=-8+5 and the product is -40=-8*5. **}\\\\\text{** So, we can factorise. **}\\\\6x^3+18x^2-240x=6x(x^2+3x-40)=6x(x^2+8x-5x-40)\\\\=6x(x(x+8)-5(x+8))\\\\\large \boxed{=6x(x+8)(x-5)}$

So, a = 5.

Thank you.
