OpenStudy (anonymous):

turn it to an equation

Parth (parthkohli):

I think it says 'expression'

Parth (parthkohli):

First tell me what the sum of x and y is

OpenStudy (anonymous):

nothing you change it into a problem

OpenStudy (anonymous):

2x + y

Parth (parthkohli):

No. I'm asking you the sum of x and y

OpenStudy (anonymous):

there is none !

Parth (parthkohli):

I mean what is the expression for the sum of x and y?

OpenStudy (anonymous):

i dont know

Parth (parthkohli):

x + y...duh

OpenStudy (anonymous):

oh lol i thought u were trying to ask me what to plug in for x and y

Parth (parthkohli):

No lol. Now tell me what's two times of that

OpenStudy (anonymous):

2(x+y)?

Parth (parthkohli):

Yay! correct :D

OpenStudy (anonymous):

can u help me with another problem?

Parth (parthkohli):

Yeah sure :)

OpenStudy (anonymous):

The product of p and -8 increased by q

Parth (parthkohli):

Oh. product of p and -8 is simply -8p. Increasing by q means adding q :)

Parth (parthkohli):

\( \color{Black}{\Rightarrow -8p + q }\)

OpenStudy (anonymous):

thank you !

Parth (parthkohli):

yw :)

OpenStudy (anonymous):

The sum of x and y, squared

OpenStudy (anonymous):

(x+y) squared?

Parth (parthkohli):

Yes

OpenStudy (anonymous):

y less than a number, x

Parth (parthkohli):

What do you think will be the answer? :)

OpenStudy (anonymous):

y-x

Parth (parthkohli):

Nope...

Parth (parthkohli):

y less than a number x would mean x - y if you think closely
