Hi there!

To solve is pretty easy. First, simplify.

21/4=(1/2x+3x) -> Combine Like Terms
21/4=7/2x
FLIP
7/2x=21/4

Multiply both sides by 2/7.
(2/7)*(7/2x)=(2/7)*(21/4)
x = 2/3

Hope this helps!

Find the value of each variable so that the quadrilateral is a parallelogram.
Dmitry [639]

Answer:

<em>x = -2</em>

<em>y = -5</em>

Step-by-step explanation:

<u>Properties of a Parallelogram</u>

  • Two pairs of opposite sides are parallel.
  • Two pairs of opposite sides are equal in length.
  • Two pairs of opposite angles are equal in measure
  • The diagonals bisect each other.
  • Adjacent angles are supplementary.
  • Each diagonal divides the quadrilateral into two congruent triangles.

Each diagonal is divided into two measures expressed with variables. Since diagonals bisect each other:

y + 23 = -4y - 2.  And

-2x + 6 = x + 12

Solve the first equation. Adding 4y:

5y + 23 = - 2

Subtracting 23:

5y = -25

Dividing by 5:

y = -5

Solve the second equation. Subtracting x and 6:

-3x = 6

Dividing by -3:

x = -2

Solution:

x = -2

y = -5

Can someone please explain to me how to solve this?
vfiekz [6]

Answer:

A

Step-by-step explanation:

√(x^5) = x^(5/2) = (x^2)√x

√9x = (√9)(√x) = (3)√x

which means: ((x^2)√x) + ((3)√x)

since both have a √x, you can factor it out. for example...if you look at A, if you apply the distributive property you can see it expands back out. hmu if you need a different. explanation
