Answer: x=5

Let’s start by rewriting the equation

4x=3x+5

Let’s combine like terms- 4x and 3x. We’ll do this by subtracting 3x on both sides.

x=5

This is your answer! Hope this helps comment below for more questions :)

Find the perimeter AND area of the parallelogram ABCD. Show all work
nexus9112 [7]

Since, this is parallelogram

so, opposite sides are equal

We will find value of sides

Calculation of AB:

we are given point A=(-2,3)

point B=(4,0)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AB=\sqrt{(4+2)^2+(3-0)^2}

AB=3\sqrt{5}

Since, this is parallelogram

so, opposite sides are equal

so,

CD=AB=3\sqrt{5}

Calculation of AD:

point A =(-2,3)

point D=(-5,2)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AD=\sqrt{(-5+2)^2+(2-3)^2}

AD=\sqrt{10}

Since, this is parallelogram

so, opposite sides are equal

so,

BC=AD=\sqrt{10}

Calculation of AE:

point A=(-2,3)

point E=(-3,1)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AE=\sqrt{(-3+2)^2+(1-3)^2}

AE=\sqrt{5}

(a)

we know that

perimeter of a parallelogram is sum of all sides

so,

perimeter is

=AB+BC+CD+DA

now, we can plug values

=3\sqrt{5}+\sqrt{10}+3\sqrt{5}+\sqrt{10}

=6\sqrt{5}+2\sqrt{10}...........Answer

(b)

we can use area of parallelogram formula

A=AE\times CD

we can plug values

A=\sqrt{5}\times 3\sqrt{5}

A=15............Answer

How do I find the value of y?
Genrish500 [490]

Answer:

y = 27

Step-by-step explanation:

line segment BA and CD are congruent, turn them into an equation

3y - 59 = y - 5

subtract 1y from both sides, you get 2y - 59 = -5

then, add 59 to both sides and the equation is now 2y = 54

divide each side by 2 and you get the value of y (y = 27)
