Question

I need 10th grade math help

Answer 1

okay...? Anything in particular?

Answer 2

ABCD is a rectangle. Find the length of each diagonal.

AC=2(x-3)
BD=x+5

Answer 3

AC and BD are the diagonals, and diagonals of a rectangle are equal to each other

2(x-3) = x + 5
the first step is to solve for x, can you do that for me please?

Answer 4

How do I do that

Answer 5

first, look at the left side of the equation

2(x-3)
distribute the 2 and tell me what you get

Answer 6

2x

Answer 7

not quite, try again

hint: A(B-C) = A*B - A*C

Answer 8

2x-6

Answer 9

right! so the left side of the equation is

2x - 6

and the right side of the equation is

x + 5

2x - 6 = x + 5
can you try solving for x now?

Answer 10

Do I subtract 6 to each side

Answer 11

Or 5

Answer 12

add 6 to both sides, since we have -6 on the left side and we want to get rid of it

Answer 13

2x=x+11 right?

Answer 14

right, now subtract x from each side

Answer 15

X=11?

Answer 16

right, x = 11, only one more step to go!

let's use the equation from before,
BD=x+5
if x = 11, what is x + 5?

Answer 17

16?

Answer 18

great! that's our answer

Answer 19

Thank you! Could you help me with a few more?

Answer 20

sure

@Vocaloid

Answer 41

Ok here's the pic

Answer 42

I suggest attaching the pic with the app
then going back to the in browser (because the app is still a little slow)

Answer 43

Find the value of Y.

Angle 1=3y+6

Answer 44

interior angle of a square is 90 degrees

3y + 6 = 90

Answer 45

Is the answer 90?

Answer 46

not quite :)

we have to solve for "Y"
when given 3y + 6 = 90

you would first subtract 6 from both sides

Answer 47

Or is it 28

Answer 48

that's correct :)

Answer 49

Could you help me with a couple more

Answer 50

of course

Answer 51

Find the measure of Angle 2

Answer 52

assuming this is a parallelogram?

Answer 53

Yes

Answer 54

just a parallelogram or square rhomus kite?
does it say anything else? :3

Answer 55

It doesn't say but the topic is Special Parallelograms

Answer 56

ohhhh then it should definitely be a ... rhombus or something

and the diagonals of a rhombus always bisect at 90 degree angles
so if it really is a rhombus, then it should be 90 degrees ^_^

Answer 57

The answer is 90?

Answer 58

I believe so, if there is no other information given

Answer 59

It was right

Answer 60

Find the measure of angle 2

Answer 61

Forget the pic I just sent can you help with this one?

RT=2x+4
SW=6x-20

Answer 62

diagonals in a rectangle are equal to each other

so 2x + 4 = 6x - 20

Answer 63

Add 6??

Answer 64

subtract 2x from both sides

Answer 65

So 4=4x-20?

Answer 66

that's right! :)

great job

now add 20 to both sides

Answer 67

24=4x

Answer 68

then divide both sides by 4

Answer 69

X=6 ??

Answer 70

mhmm

Answer 71

Find the measure of angle 1

Answer 72

assuming angle 1 equals angle 2

there are 360 degrees in a quadrilateral
360 = 2*104 + 2*(2[angle 1])

360 = 208 + 4 [angle 1]

now subtract 208 from both sides

Answer 73

152=4?

Answer 74

Divide by 4

Answer 75

38??

Answer 76

that's what I got :)

Answer 77

So it's right

Answer 78

RZ=30
SW=5x-20

Answer 79

2(RZ) = (SW)

2(30) = 5x - 20

Answer 80

Is the answer 16

Answer 81

yup

Answer 82

It was wrong

Answer 83

Find the measure of angle 4

Answer 84

it was wrong and yet you still ask me? xD
perhaps you should try opening a new question to get someone to help you
I'm not actually good at these :-/

Answer 85

You've been getting them all right though

Answer 86

what I'm saying is
idk how to do this one, sorry o-o
