Answer:
Total Dolls would Evelyn have had if she had not lost them = 9 Dolls
Step-by-step explanation:
As given,
Total dolls Evelyn had = 9
Total dolls lost = 
× 9 = 3
So, Now
Evelyn had total dools after lost = 9 - 3 = 6
If she had not lost te dolls , then she had 3 dolls more
∴ we get
If she had not lost any dolls , Evelyn had total dolls = 6 + 3 = 9
So, The answer would be :
Total Dolls would Evelyn have had if she had not lost them = 9 Dolls
The expression of the polynomials with like terms grouped together is (c) [-4x²] + 2xy² + [10x²y + (-4x²y)]
<h3>How to group the polynomial by like terms?</h3>
We have:
10x²y + 2xy² - 4x² - 4x²y
Collect the like terms
- 4x² + 2xy² + 10x²y - 4x²y
Put each group in bracket
- 4x² + 2xy² + [10x²y - 4x²y]
Express as positives
[-4x²] + 2xy² + [10x²y + (-4x²y)]
Hence, the expression of the polynomials with like terms grouped together is (c) [-4x²] + 2xy² + [10x²y + (-4x²y)]
