-4x^2 - 6

When you add them together it gives a sum of -2x^2 - 6. Multiplying that by 2 gives you the above answer.

Put the equation in standard form with a positive x coefficient. 2y+5=-4(x+2)
umka21 [38]

The standard form of equation is: 4x+2y = -13

Step-by-step explanation:

the standard form of a linear equation in two variables is given by:

ax+by = c

Given equation is:

2y+5=-4(x+2)

Distributing -4 into the round bracket

2y+5 = -4x-8

Adding 4x on both sides

4x+2y+5 = -4x-8+4x\\4x+2y+5 = -8

subtracting 5 from both sides

4x+2y+5-5 = -8-5\\4x+2y = -13

The standard form of equation is: 4x+2y = -13
