Find the value of x.

slavikrds [6]

Answer:

$x=11$

Step-by-step explanation:

we know that

The Midpoint Theorem states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

In this problem

$(x+5)=\frac{1}{2}(3x-1)$

solve for x

Multiply by 2 both sides

$2x+10=3x-1$

subtract 2x both sides

$10=3x-1-2x$

$10=x-1$

Adds 1 both sides

$x=11$

BEST GETS BRAINLEST.

sashaice [31]

We know that the given side lengths are x and the height is x.

Therefore, the area of the base = $A = x * x$

$Formula =\ \textgreater \ volume = length*width*height
$

$To \ find \ the \ volume \ of \ 1 \ slab, \ multiply \ by \ the \ height$ $x -3$

$= x*x*(x-3)$

$Volume \ of \ 25 \ slabs =$ $25*x^2*(x-3)=350000$

$350,000/25 = 14,000$ 

$x^3 - 3x^2 - 14000$ 

$= 25.14$

 $
Rounded => x=25$
