Answer:
3x²y (2x²-3y²+ 4y)
Step-by-step explanation:
Factor the expression 6x^4y-9x²y³+12x²y².
First, check if there is a GCF. The GCF is 3x²y.
3x²y (2x²-3y²+ 4y).
This equation cannot be factored further. Therefore, the answer is
3x²y (2x²-3y²+ 4y).
Hope this helps!
Answer:
A) The following are true:
2+4x=2(2x+1)
2+4x=2⋅2x+2⋅1
2+4x=4x+2
2+4x−4x=4x−4x+2
2=2
B)
There are infinitely many solutions.
The equation is an identity
The solution is 2.
The equation is true for all values of x.

The grade of a road is the slope of a road. In the U.S., grade is often expressed as a percent by finding the product 100(slope). Approximate the grade of a road that has a rise of 950 ft over 3 mi is :
A. 3%
The formula for density = number/ area
In this case number=20
area = 5m^2
Density = 20/5=4 mice per m^2
The right answer is <span>A. 4 per m2</span>
Answer:
r ≥ 20
Step-by-step explanation:
r/3 - 9 ≥ - 2
r/3 ≥ 7
Multiply both sides by 3
r ≥ 21
