\bf \cfrac{hotdogs}{hamburgers}\qquad 8:1\qquad \cfrac{8}{1}\qquad \cfrac{8\cdot \frac{72}{8+1}}{1\cdot \frac{72}{8+1}}\implies \cfrac{8\cdot 8}{1\cdot 8}\implies \cfrac{64}{8}

How do I solve this?
vodomira [7]
I’m assuming what you’re asking here is how to *factor* this expression. For that, let’s rearrange the expression into a more familiar form:

-c^2-4c+21

From here, we’ll factor out a -1 so that we have:

-(c^2+4c-21)

Let’s focus on the quadratic expression inside the parentheses. To find our factors (c + x)(c + y), we’ll need to find two terms x and y that multiply together to make -21 and add together to make 4. It turns out that the numbers -3 and 7 work out perfectly for that purpose (-3 x 7 = -21 and 7 + (-3) = 4), so substituting them in for x and y, we have:

(c + (-3))(c + 7)
(c - 3)(c + 7)

And adding back on the negative from a few steps earlier:

-(c - 3)(c + 7)

What property out of distributive,communitive,and associative.
Vlad1618 [11]
Hello!

The Associative Property of Multiplication states the following:

a × (b × c) = (a × b) × c

The equation given in the image above follows the same form:

9 × (5 × 2) = (9 × 5) × 2

Therefore, the given equation must be representative of the Associative Property.

I hope this helps!
