Answer:

x^3 - 13x^2.

Step-by-step explanation:

–(5x3 + x2) + 4(x3 – 3x2) Removing the brackets:-

= -5x^3 - x^2 + 4x^3 - 12x^2

= -5x^3 + 4x^3 - x^2 - 12x^2

= x^3 - 13x^2.

6x=1/2(2X +7)<br> Solve for x

Daniel [21]

Answer:

Step-by-step explanation:

6x=1/2(2x +7) Multiply both sides by 2

2*6x = 1/2(2x + 7)*2

12x = 2x + 7 Subtract 2x from sides

12x-2x =2x-2x+7

10x = 7 Divide by 10

x = 7/10

x = 0.7

Let's check it

6(0.7) = 4.2

1/2 (2*0.7 + 7)

1/2 (1.4 + 7)

1/2 ( 8.4)

4.2

Both sides check. The answer must be x = 0.7
