➽━━━━━━━━━━━━━──➸

☺ 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______❤

Find the value of x.
BartSMP [9]

Answer:

56

Step-by-step explanation:

We know that every triangle no matter will equal 180 degrees. So we will make an algebreic expression.

2x+8+60=180

When doing algebreic expression we want to simply as much as possible to find our answer. First we will do 60-180. Since the expression is adding 60 we want to do the opposite and subtract is by 60 on both sides. SO now we have 2x+8=120. We do the same thing with 8. Subtract it on  both sides since its adding in the expression. Now we have 2x=112. FInally, we will divide by two on both sides since its multiplying on the other side of the equation. So now we are left with x=56.
