➽━━━━━━━━━━━━━──➸

☺ Hello mate__ ❤

◾◾here is your answer...

i think right question is this

(3x − 7y)^2

ok now start solving:-

(3x − 7y)^2

=> (3x − 7y) (3x − 7y)

=> 3x(3x- 7y) -7y(3x-7y)

=>. 3x.3x - 3x.7y-7y. 3x + 7y.7y

=> 9x^2 -27xy +27xy + 49y^2

=> 9x^2 + 49y^2

so your correct ans. is 9x2 + 49y2

➽━━━━━━━━━━━━━──➸

I hope, this will help you.☺

Thank you______❤

–2x + 1 – (–7x + 3) = –4 + 3(x – 2)
natali 33 [55]

Answer:

x = -4

Step-by-step explanation:

–2x + 1 – (–7x + 3) = –4 + 3(x – 2)

-2x + 1 + 7x - 3 = -4 + 3x - 6

-2x + 7x - 3x = -4 - 6 - 1 + 3

2x = -8

x = -8/2

x = -4

How do you graph an inequality on the number line if they are the same number? Using "and"
Korvikt [17]

If the sign looks like > or <, it excludes the number, if there is a line under the < or >, it is inclusive, which means at least, or at most. To display inclusive draw a circle on the point and fill it in, for exclusive, draw a circle and don't fill it in.
