common denominator first. multiply 2/5 by 2 in the top and bottom so they all have a denominator of 10
7/10+4/10-1/10=10/10
10/10=1
7/10+4/10-1/10=10/10
10/10=1
Assuming mental math still follows the order of operations, you have
So the answer is 1.
So the answer is 1.
1. 12x - 3x^2
2. 20 - 240x^2
Answers
Answer:
1. 3x(4-x)
2. 20(1-12x^2)
Step-by-step explanation:
1. Both of the monomials have an x and can be divided by 3. You can factor out 3x, getting the equation I wrote out on the answer part.
2. Both of the monomials can be divided by 20, so you can once again factor out 20, getting the equation I wrote out on the answer part.
