Question

-15xy-(2c+8x)+3x(5y+6)+2

Answer 1

Відповідь:

-15xy-(2c+8x)+3x(5y+6)+2= -15xy-2c-8x+15xy+18х+2= (-15ху+15ху)+(-8х+18х)-2с+2= 0+10х-2с+2= 10х-2с+2= 2(5х-с+1)

Покрокове пояснення:

Answer 2

To simplify the expression -15xy - (2c + 8x) + 3x(5y + 6) + 2, let's break it down step by step:

Step 1: Distribute 3x to (5y + 6) -15xy - (2c + 8x) + 3x(5y + 6) + 2 = -15xy - (2c + 8x) + 15xy + 18x + 2

Step 2: Combine like terms (-15xy + 15xy) + (-8x + 18x) + (-2c + 2) = 0 + 10x + (-2c + 2) = 10x - 2c + 2

So the simplified form of the expression -15xy - (2c + 8x) + 3x(5y + 6) + 2 is 10x - 2c + 2.
