Answer:

  • Parallelogram

Step-by-step explanation:

  • ED = FG = 4, easy to calculate
  • ED ║ FG, both are vertical line segments
  • EF = DG = √5²+1²= √26
  • EF ║ DG as the slopes are same
  • m(EF) = (7-6)/(6-1) = 1/5
  • m(DG) = (3-2)/(6-1) = 1/5

As we see the opposite sides are parallel and congruent. This is the property of a parallelogram

Solve for x:<br> 4(1 – x) + 2 x = -3( x + 1)
valentinak56 [21]

Answer:

<u>4(1 – x) + 2 x = -3( x + 1)</u>

first do 4 time 1= 4

then do 4 times x =4x

now the equation should look like this

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

then do the other side of the equation

-3(x+1)

=-3x-3

Now collect the like terms:

-4x-2x

now the equation should look like this

4-2x=-3x-3

now add 3x add on both sides

4-2x+3x=-3

put the 4 on the other side

-2x+3x=-3-4

now again collect the like terms (-2x+3x=1 which is just x and -3-4 =-7)

x=-7

answer

x=-7
