did i asnwer them correctly

hushed idol Nov 23, 2023, 9:20 AM

#

5 - 8 is not 5

#

and 7y + 2y is not 1y

neon forge Nov 23, 2023, 9:21 AM

#

5-8 is ,-3

sleek steeple Nov 23, 2023, 9:21 AM

#

huh

#

what

#

how do i simplify

hushed idol Nov 23, 2023, 9:22 AM

#

reorder the terms until the like terms are next to each other, then you combine the numbers associated with that term

#

the first one you did correctly

#

5a + 7c + 3a + 1c
5a + 3a + 7c + 1c
(5+3) = 8, (7+1) = 8
8a + 8c

sleek steeple Nov 23, 2023, 9:23 AM

#

so e)
9y-3?

hushed idol Nov 23, 2023, 9:23 AM

Calculate correctly

sleek steeple Nov 23, 2023, 9:25 AM

hushed idol Nov 23, 2023, 9:25 AM

#

sleek steeple Nov 23, 2023, 9:25 AM

#

#

9a and 3q arent like terms

hushed idol Nov 23, 2023, 9:28 AM

#

q is not a thing

sleek steeple Nov 23, 2023, 9:28 AM

#

holy

#

im tripping

#

sorry

#

mb

#

what if there was another letter though

hushed idol Nov 23, 2023, 9:29 AM

#

well then you would not combine them

sleek steeple Nov 23, 2023, 9:29 AM

#

if it was 3q would that be correct

hushed idol Nov 23, 2023, 9:29 AM

#

yes

sleek steeple Nov 23, 2023, 9:29 AM

#

👍

#

how this work

hushed idol Nov 23, 2023, 9:29 AM

#

you can also change the order with multiplication

#

so just move all the numbers together

sleek steeple Nov 23, 2023, 9:30 AM

#

45 xy?

#

wym by that

hushed idol Nov 23, 2023, 9:30 AM

#

nah, 4*x*5*y = 4*5*x*y

#

4*5 is 20

sleek steeple Nov 23, 2023, 9:31 AM

#

so

#

45

#

4x5

#

20

#

20xy

#

?

hushed idol Nov 23, 2023, 9:31 AM

#

yes

sleek steeple Nov 23, 2023, 9:32 AM

#

so i qrite 20xy

#

or 20*xy

#

?

#

pyroooooooooo

hushed idol Nov 23, 2023, 9:36 AM

#

20xy is shorter, so use that

#

both are correct

sleek steeple Nov 23, 2023, 9:36 AM

#

👍

#

ok now

#

14gh/7h

#

how er simplify this

hushed idol Nov 23, 2023, 9:37 AM

#

what's 14/7

sleek steeple Nov 23, 2023, 9:37 AM

#

2

#

2*gh h

hushed idol Nov 23, 2023, 9:38 AM

#

now h/h cancels out if h is not 0

#

so you can probably just write 2g

sleek steeple Nov 23, 2023, 9:38 AM

#

ok

#

hb this

#

hushed idol Nov 23, 2023, 9:40 AM

#

sleek steeple Nov 23, 2023, 9:40 AM

#

hm

#

3x4

#

12

#

12x3 y?

#

12 x3y

#

pyro am i right

hushed idol Nov 23, 2023, 9:41 AM

#

yeah

#

if by x3 you mean x cubed

sleek steeple Nov 23, 2023, 9:42 AM

#

yes

#

ill try do the divide

#

i think i got something wrong

hushed idol Nov 23, 2023, 9:45 AM

#

yeah when you divide, the exponents subtract, not add

sleek steeple Nov 23, 2023, 9:46 AM

#

show me

#

i dont understand this math language

#

😭

hushed idol Nov 23, 2023, 9:46 AM

#

like in this case

#

$\frac{y^3}{y^2} = \frac{y\times y\times y}{y\times y} = \frac{y\times\cancel {y\times y}}{\cancel{y\times y}} = y$

Pyrokinetics

sleek steeple Nov 23, 2023, 9:47 AM

#

hushed idol Nov 23, 2023, 9:47 AM

sleek steeple Nov 23, 2023, 9:47 AM

hushed idol Nov 23, 2023, 9:47 AM

#

sleek steeple Nov 23, 2023, 9:47 AM

sleek steeple Nov 23, 2023, 9:54 AM

#

what does expand mean

#

:(

#

can you do a step by step for me

#

🙏

hushed idol Nov 23, 2023, 9:54 AM

#

it means distribute

sleek steeple Nov 23, 2023, 9:55 AM

#

show plez

hushed idol Nov 23, 2023, 9:55 AM

#

like 5(x+5) = 5*x + 5*5

sleek steeple Nov 23, 2023, 9:57 AM

#

..........

sleek steeple Nov 23, 2023, 9:58 AM

#

hushed idol like 5(x+5) = 5*x + 5\*5

how does 5(x+5) turn into 5x + 55

#

can you tell me the process

#

pyro

hushed idol Nov 23, 2023, 10:01 AM

#

multiplication distributes over addition

#

you can think about a rectangle

#

sleek steeple Nov 23, 2023, 10:03 AM
