Question

1.3a(2b+c)+8b+4c 2.2x(3x-4y)-6x+8y

Answer 1

Ответ:

1.1/10×(2b+c)×13a+40)

2.1/5×(3x-4y)×(11x-10)

Пошаговое объяснение:

1.13/10a×(2b+c)+8b+4c

13/10a×(2b+c)+4(2b+c)

(2b+c)×(13/10a+4)

(2b+c)×1/10×(13a+40)

2.11/5x×(3x-4y)-6x+8y

11/5×(3x-4y)-2(3x-4y)

(3x-4y)×(11/5x-2)

(3x-4y)×1/5×(11x-10)

Answer 3

Let's simplify the given expressions:

1. 1.3a(2b+c) + 8b + 4c

To simplify this expression, we can distribute the 1.3a to both terms inside the parentheses:

1.3a(2b+c) = 2.6ab + 1.3ac

Now we can rewrite the expression:

2.6ab + 1.3ac + 8b + 4c

We can further simplify it by grouping like terms:

(2.6ab + 8b) + (1.3ac + 4c)

Factoring out common terms:

2b(1.3a + 4) + c(1.3a + 4)

Finally, we can rewrite the expression in a simplified form:

2b(1.3a + 4) + c(1.3a + 4)

2. 2.2x(3x-4y) - 6x + 8y

First, let's simplify the expression inside the parentheses:

3x - 4y

Now we can rewrite the expression:

2.2x(3x-4y) - 6x + 8y

Distribute the 2.2x to both terms inside the parentheses:

(2.2x * 3x) - (2.2x * 4y) - 6x + 8y

Simplify the multiplication:

6.6x^2 - 8.8xy - 6x + 8y

Now we can group like terms:

(6.6x^2 - 6x) + (-8.8xy + 8y)

Factor out common terms:

6x(1.1x - 1) - 8y(1.1x - 1)

Finally, we can rewrite the expression in a simplified form:

6x(1.1x - 1) - 8y(1.1x - 1)
