Question

А) 2с-3d с-5d 3c+4d ______ + _____ _ _____ 4с 4c 4c​

Answer 1

Не уверен точно, но возможно так

Answer 2

To simplify the expression, let's combine like terms and perform arithmetic operations:

Given expression: $2c - 3d + c - 5d + 3c + 4d$

Step 1: Combine like terms Combine the coefficients of $c$ and $d$ separately:

$2c + c + 3c = 6c$ (coefficients of $c$ terms) $-3d - 5d + 4d = -4d$ (coefficients of $d$ terms)

So, the expression becomes: $6c - 4d$

Step 2: Combine with the other terms The expression is now: $6c - 4d + 4c + 4c$

Combine the coefficients of $c$ terms:

$6c + 4c + 4c = 14c$

So, the final simplified expression is $14c - 4d$.
