Mathematics

3 0

Answer:

32x^3+4x^2+41x-35

Step-by-step explanation:

We have these two polynomials

(8x-5)(4x^2+3x+7)

Now we need to distribute one polynomial to all of the terms to the other.

32x^3+24x^2+56x-20x^2-15x-35

Next we can combine all of the like terms

32x^3+24x^2+56x-20x^2-15x-35\\\\32x^3+4x^2+41x-35

At the frozen yogurt shop, Colin pays $3.28 for his treat, which weighs 8 1/5 ounces. What is the unit cost (Cents per ounce)?
Arturiano [62]

Hi!

3.28$ = 328 cents

8 1/5 ounces = 41/5 ounces

We will find the unit cost, cents per ounce, using proportions, like this:

328 cents for 41/5 ounces

x cents for 1 ounce

________________________

x = (328*1)/(41/5)

x = 328/(41/5)

x = (328*5)/41

x = 1640/41

x = 40

Unit cost = 40 cents per ounce.

Hope this helps!
