Answer:
(-13,-7)
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
1 1/3 = 4/3
4/3 - 1/3
drop the bottom 3 since it is a common denominator
4 - 1 = 3
bring the 3 back
3/3 = 1
Answer:
144
Step-by-step explanation:
Mutiply the 3 numbers to get the volume
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)
