<span>-28x²-12x = -4x(7x+3) the first one is answer</span>
the correct option is answer choice D, because there are multiple 2's in the x column with different f(x) values.
First we have to isolate the varible
-2/5x-2=18
+2 +2
-2/5x=20
then divide both sides by -2/5 to get x completely by itself
-2/5x=20
------- ---
-2/5 -2/5
x=-50
i hope i've helped!
Answer:
5 5/7
Step-by-step explanation:
-4*6/7*-5/3
We can multiply the numerators
-4 * 6*-5 = 120
We can multiply the denominators
7*3 =21
Put the numerator over the denominator
120/21
The top and bottom are both divisible by 3
120/3 = 40
21/3 =7
The new improper fraction is 40 /7
Changing from an improper fraction to a mixed number
7 goes into 40 5 times with 5 left over
5 5/7
