Solve for x. Show all work. (10 points) 4(2x + 1) - 3= -3(x – 4

Ann [662]

Hello there!

4(2x + 1) - 3 = -3(x - 4)

We need to distribute both sides

(4)(2x) + (4)(1) - 3 = (-3)(x) + (-3)(-4)

8x + 4 - 3 = -3x + 12

8x + 1 = -3x + 12

Now subtract 1 from both sides

8x + 1 - 1 = -3x + 12 - 1

8x = -3x + 11

Add 3x to both sides

8x + 3x = -3x + 11 - 3x

11x = 11

x = 11/11

x = 1

I hope this helps~!

Good luck with your career!

Find the length of AB. A. 2 B. 6 C. 21 D. 31

Allushta [10]

Answer

AB=21

Solution

In the triangle ABC two lines are parallel to side AC.In a triangle a line passing through two side and it is parallel to third side,then this line divides two side in equal ratio.

Here we take any of the parallel line, passing through AB and AC, and parallel to BC.

So we can write, $\\$ $\frac{ 6x+2x+1}{2x}$ = $\frac{18+7.5}{6}$
