Answer:
(x-2)(3x²-4 )
Step-by-step explanation:
- First, you <u>multiply 3x and 8</u> to equal 24x²
- Then, you find the variables that equal -10x (-2x, and -12x)
- then <u>replace the -10x with the two variables you found</u> (3x²-2x-12x+8)
- Sperate the variable (3x²-2x) and (-12x+8)
- Find the <u>GCF</u> of both x(3x-2) and -4(3x-2) (the binomial in the parentheses MUST BE THE SAME
- Replace one of the parentheses with x-4
- Answer: (x-2) (3x-4)
Answer:
Number:3.75
Equation:7 x-9=3(x+2)
Step-by-step explanation:
Let the number be x.
According to the question,
7 x-9=3(x+2)
7 x-9= 3 x+ 6
7 x- 3 x= 9+6
4 x= 15
x=15/4
x=3.75
If you verify the answer you will get,
11.25=11.25
