8x+5y+20x+6y+3=?, 20+6b+3ab +5b+10=?, 4x+4x 2+3+5x+x2 +7=?,21+5a2b+4ab2+a2b =?, 8+xy+2+xy2+3xy+x2y=?

Answer 1

Держи) во втором два решения , т.к я не поняла есть ли знак в третьем примере или нет)

Answer 2

8х+5у+20х+6у+3=28х+11у+3
20+6b+3ab+5b+10=30+3ab+11b
4x+8x+3+5x+x14=26x+3
21+5a2b+4ab2+a2b =21+20ab
8+xy+2+xy2+3xy+x2y=10+8xy

Answer 3

Let's simplify each expression step by step:

1. 8x + 5y + 20x + 6y + 3: Combine like terms: = (8x + 20x) + (5y + 6y) + 3 = 28x + 11y + 3

2. 20 + 6b + 3ab + 5b + 10: Combine like terms: = (20 + 10) + (6b + 5b) + 3ab = 30 + 11b + 3ab

3. 4x + 4x^2 + 3 + 5x + x^2 + 7: Combine like terms and simplify exponents: = (4x + 5x) + (4x^2 + x^2) + (3 + 7) = 9x + 5x^2 + 10

4. 21 + 5a^2b + 4ab^2 + a^2b: Combine like terms: = 21 + a^2b + 5a^2b + 4ab^2 = 21 + 6a^2b + 4ab^2

5. 8 + xy + 2 + xy^2 + 3xy + x^2y: Combine like terms: = 8 + 2 + (xy + 3xy) + xy^2 + x^2y = 10 + 4xy + xy^2 + x^2y

So, the simplified expressions are:

1. 28x + 11y + 3
2. 30 + 11b + 3ab
3. 9x + 5x^2 + 10
4. 21 + 6a^2b + 4ab^2
5. 10 + 4xy + xy^2 + x^2y
