Question

2) 4(2 + x) - 3(1 + x); 4) 11(5c+d)+3(d+c).

Answer 1

Ответ:

2) 5+х

4) 58c+14d

Пошаговое объяснение:

2) 4*(2+х)-3*(1+х)= 8+4х-3-3х=5+х

4) 11*(5с+d)+3*(d+c)=55c+11d+3d+3c=58c+14d

Answer 2

Ответ:

Пошаговое объяснение:

8+4x-3+x=5+3x

55c+11d+3d+3c=58c+14d

Answer 3

It looks like you've provided two algebraic expressions. Let's simplify each of them step by step:

1. $4(2 + x) - 3(1 + x)$:

Distribute the constants and variables within the parentheses:

$8 + 4x - 3 - 3x$

Combine like terms:

$8 - 3 + 4x - 3x$

Simplify the constants:

$5 + x$

So, $4(2 + x) - 3(1 + x)$ simplifies to $5 + x$.

2. $11(5c + d) + 3(d + c)$:

Distribute the constants and variables within the parentheses:

$55c + 11d + 3d + 3c$

Combine like terms:

$55c + 3c + 11d + 3d$

Simplify the coefficients:

$58c + 14d$

So, $11(5c + d) + 3(d + c)$ simplifies to $58c + 14d$.
