Question 4 Multiple Choice Worth 1 points)<br> (01.02 MC)<br> Solve for :<br> 2 x -<br> (x - 2) = 4x
oee [108]

Answer:

\small \sf \frac{2}{3}   = x \\

Step-by-step explanation:

Solve for x;

2x - ( x - 2 ) = 4x

distribute minus sign through parantheses

  • 2x - x + 2 = 4x

combine like terms

  • x + 2 = 4x

subtract x from both side

  • x - x + 2 = 4x - x
  • 2 = 3 x

Divide each side by 3

\small \sf \frac{2}{3}  =  \frac{3x}{3} \\

\small \sf \frac{2}{3}  = x\: \\

I need the answer fast I am in schoool pls
Stolb23 [73]

Answer:

288

Step-by-step explanation:

To solve, we need to find the area of the four triangle sides and add that to the square base's area.

Area of triangle sides: base * height * 0.5

Area of square base: base * height

Substitute the values

8 * 14 * 0.5 = 56

There are four of these sides, so the area of all the triangles is 224.

The square base is 8 * 8, or 64

Add these two values together.

64 + 224 = 288

Thus, the answer is 288
