Answer:
Step-by-step explanation:
First, we change both denominators to the LCM (lowest common multiple) which is 8.
Since the denominators are the same, we can add the numerators.
or it can be written as
Answer is A.
step 1 , 16 was not multiplied by 9
should be
54x - 9y = 144
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)
0.52 because 52/100 is better than 52/1000 and 52/10000
