4x + 2 - 3x + 5 - 2(x + 5) = (2x - 5) + (3x + 4) 
4x + 2 - 3x + 5  - 2x - 10 =   2x - 5 +   3x + 4 
4x - 3x - 2x + 5 + 2 - 10  =  2x + 3x - 5 + 4 
        - x             - 3           =       5x       - 1   
-x - 3 = 5x - 1 is the line above recopied 
+x     = +x       
    -3   = 6x - 1 
<span>    +1   =    + 1 </span>
    - 2   = 6x 
    - 2/6 = 6x/6 
    - 1/3 = x, the answer

Given: segment AB || segment DE, C is the midpoint of segment DB. Prove: ΔACB ≅ ΔECD Fill in the missing reason for the proof. A
OleMash [197]

Answer:

Given: Segment AB || segment DE, C is the midpoint of segment DB.

Prove: ΔA CB ≅ ΔE CD

Proof: In ΔA CB and ΔE CD

 C is the Mid point of B D.

BC=C D→ definition of midpoint

∠A CB= ∠ EC D→→vertical angles are congruent

∠BAC=∠DEC→→[AB║DE,so alternate angles are equal]

→→ΔA CB ≅ ΔE CD[A AS or A SA]

Option B: vertical angles are congruent

What is the area of a parallelogram ABCD
svetoff [14.1K]

Answer:

Area of a parallelogram would be 13.46

Step-by-step explanation:

Since area of a parallelogram is represented by the formula

Area = \frac{1}{2} ((D_{1}*D_{2})

Where D_{1} and D_{2} are two diagonals of the given parallelograms.

In the given figure D_{1}=AC and D_{2} = BD

We will find the length of D_{1} and D_{2} first

Since points A and C are (3,6) and (5,1)

So distance AC = \sqrt{(6-1)^{2}+(3-5)^{2}  }

= \sqrt{5^{2}+(-2)^{2}}

= \sqrt{25+4}=\sqrt{29}

Since B and D are the points (6, 5) and (2, 2)

So length of BD = \sqrt{(6-2)^{2}+(5-2)^{2}}

BD = \sqrt{4^{2}+3^{2}}=\sqrt{25}=5

Now we will put these values in the formula

Area of parallelogram = \frac{1}{2}(\sqrt{29})(5)

= \frac{5}{2} × \sqrt{29}

= (2.5) (5.385)

= 13.46

Find the slope of the line going through the points 2, -3 and -1, 15
Evgen [1.6K]

Answer:

<h2>-6</h2>

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have two points (2, -3) and (-1, 15).

Substitute:

m=\dfrac{15-(-3)}{-1-2}=\dfrac{15+3}{-3}=\dfrac{18}{-3}=-6
