help please

Answer 1

Answer 2

Set the two sides equal to each other. So it would be
8x - 5 = 6x + 9
Then, solve for x

Answer 3

And yes, opposite sides on rhombus are equal.

Answer 4

To add onto what @steve816 we set the two equations equal to each other because the sides of are equal to each other. We know this because the shape is a parallelogram some properties of a parallelogram include:
-parallel sides <----in this case the sides are parallel :)
-opposite sides are congruent
- diagonals bisect each other

Answer 5

i cant find whats X...

Answer 6

Do you know how to combine like terms?
8x - 5 = 6x + 9
Subtract 6x to both sides, you get
2x - 5 = 9
Add 5 to both sides, you get
2x = 14
Can you solve for x now?

Answer 8

Yup! Good job :)

Answer 9

okay i got a 100 on it!

Answer 10

now just one more bonus question for a fan!

hi

Answer 14

hi

Answer 15

This should help...

According to the chart `DG` is `1/3 of AD` and `AG is 2/3 of AD`

Answer 16

I agree

Answer 17

not that well with fractions......

Answer 18

`AD` equals `45cm`.

\(\huge\bf{AG=\frac{45 \times 2}{3}}\)

\(\huge\bf{DG=\frac{45}{3}}\)

Answer 19

bonus bonus question!!!!

Answer 20

@563blackghost @Daniyil_the_spy

Answer 21

im right.

Answer 22

Parallelograms have two parallel pairs that are opposite from each other.

So we would have to find the slope of each. Let's do Sarah's first.

Sarah's guesswork:

\(\huge\bf{AB=\frac{6-1}{1-4}}\)

\(\huge\bf{BC=\frac{4-6}{-4-1}}\)

\(\huge\bf{CD=\frac{-1-4}{-1+4}}\)

\(\huge\bf{DA=\frac{-1-1}{-1-4}}\)

Justin's guess work:

\(\huge\bf{AC=\frac{4-1}{-4-4}}\)

\(\huge\bf{BD=\frac{3-6}{9-1}}\)

\(\huge\bf{BC=\frac{4-6}{-4-1}}\)

\(\huge\bf{DA=\frac{3-1}{9-4}}\)

Answer 23

Sorry it's quite long. I took a while cause I was making sure the equation were correct.

Answer 24

is it okay if i have the complete versions of the division problems/fractions? like i said, im not good at them...

Answer 25

@563blackghost

Answer 26

Sorry I can not do that :(

I can check if you do them correctly, just post up the solutions you got ;)

Answer 27

can you at least help me along with every one of them?

Answer 28

Sarah's guesswork:

\(\huge\bf{AB=\frac{6-1}{1-4}}\)

Let's first subtract.

\(\huge\bf{AB=-\frac{5}{3}}\)

That's the slope of `AB`.

Answer 29

ok

Answer 30

\(\huge\bf{BC=\frac{4-6}{-4-1}}\)

We subtract to...

\(\huge\bf{BC=\frac{-2}{-5} \rightarrow \frac{2}{5}}\)

Answer 31

\(\huge\bf{CD=\frac{-1-4}{-1+4}}\)

Subtract.

\(\huge\bf{CD=-\frac{5}{3}}\)

Answer 32

\(\huge\bf{DA=\frac{-1-1}{-1-4}}\)

Subtract.

\(\huge\bf{DA=\frac{-2}{-5} \rightarrow \frac{2}{5}}\)

Answer 33

okay

Answer 34

do i put it in the calculator?

Answer 35

Yea that works to solve for the slope. Just place it right.

EX.
`(-1-1)/(-1-4)`

Answer 36

so the answer to the ex is 2/5 right?

Answer 37

Correct :)

Due to the fact `DA = BC` and `AB = CD` her point does make it in a parallelogram. Now we check Justin's. Can you possibly do this?

Answer 38

can we work on the others then?

Answer 39

\(\huge\bf{AC=\frac{4-1}{-4-4}}\)

Subtract.

\(\huge\bf{AC=-\frac{3}{8}}\)

Answer 40

\(\huge\bf{BD=\frac{3-6}{9-1}}\)

\(\huge\bf{BD=-\frac{3}{8}}\)

Answer 41

\(\huge\bf{BC=\frac{4-6}{-4-1}}\)

Subtract.

\(\huge\bf{BC=\frac{-2}{-5} \rightarrow \frac{2}{5}}\)

Answer 42

\(\huge\bf{DA=\frac{3-1}{9-4}}\)

\(\huge\bf{DA=\frac{-2}{-5} \rightarrow \frac{2}{5}}\)

Answer 43

Due to the fact `AC = BD` and `BC = DA` then Justin's point does make it into a parallelogram.

So what is your conclusion?
