Question

346) 1) a(m+n)+b(m+n);2) b(a +5)-c(a +5);3) a(b-5)-(b-5);4) (y - 3)+ b(y - 3).​

Answer 1

Объяснение:

346.

1)=(m+n)(a+b)

2)=(a+5)(b-c)

3)=(b-5)(a-1)

4)=(y-3)(1+b)

Answer 2

It looks like you want to simplify these algebraic expressions. I'll simplify each one for you:

1. a(m+n) + b(m+n): You can factor out (m+n) from both terms: (m+n)(a+b)

2. b(a + 5) - c(a + 5): Again, factor out (a + 5) from both terms: (a + 5)(b - c)

3. a(b - 5) - (b - 5): You can factor out (b - 5) from both terms: (b - 5)(a - 1)

4. (y - 3) + b(y - 3): Factor out (y - 3) from both terms: (y - 3)(1 + b)

So, the simplified expressions are:

1. (m+n)(a+b)
2. (a + 5)(b - c)
3. (b - 5)(a - 1)
4. (y - 3)(1 + b)
