What’s the length of the segments variable expressions ??

maxonik [38]

Answer:

$EF=9\ units$

Step-by-step explanation:

we know that

The <u><em>Trapezoid Mid-segment Theorem</em></u> states that: A line connecting the midpoints of the two legs of a trapezoid is parallel to the bases, and its length is equal to half the sum of lengths of the bases

so In this problem

$EF=\frac{1}{2}[AD+BC]$

substitute the given values

$x=\frac{1}{2}[(x-6)+(2x-3)]$

$x=\frac{1}{2}[3x-9]$

$2x=(3x-9)\\3x-2x=9\\x=9$

$AD=x-6=9-6=3\ units$

$EF=x=9\ units$

$BC=2x-3=2(9)-3=15\ units$

Help plsssssss WILL GIVE BRAINLIEST

ruslelena [56]

Answer: (1,2)

Step-by-step explanation:

I will help you..

Given:

$-2x-5y=-12\\10x-4y=2$

Lets cancel out the x term..

$5(-2x-5y)=-12(5)\\=-10x-25y=-60$

Now our system looks like this:

$-10x-25y=-60\\10x-4y=2$

Add.

$-29y=-58\\y=2$

plug in 2 for y

$-2x-5(2)=-12\\-2x-10=-12\\-2x=-2\\x=1$

Therefore the system is:

$(1, 2)$

If this helped consider marking brainiest.

How do you know if 2 polygons are similar?

faltersainse [42]

Check the angles and corresponding sides: All the angles in a rectangle are congruent to each other and now check that the sides are proportional to each other. 2. Scale factor: If two polygons are similar, then the ratio of the lengths of the two corresponding sides is the scale factor.
