Use Use an element argument to prove the state (A-B)U(ANB) = A" is true. he statement "For all sets A and B,

lys-0071 [83]

Answer with Step-by-step explanation:

We have to prove that

$(A-B)\cup (A\cap B)=A$ is true for all sets A and B

Let $x\in(A-B)\cup (A\cap B)$

Then $x\in(A-B)$ or $x\in(A\cap B)$

$x\in A$ and $x\notin B$ or $x\in A\;and\; x\in B$

Hence, $x\in A$

Conversely ,Let $x\in A$

Then x belongs to A and x does not belongs to B then

x belongs to A- B

Or x belongs to A and x belongs to B then x belongs to $A \cap B$

Hence, $x\in( A-B)\cup (A\cap B)$

Therefore, $(A-B)\cup (A\cap B)=A$

Expand. If necessary, combine like terms. (3 + 4x) (3 - 4x)

shepuryov [24]

(3 + 4x) (3 - 4x)

We know the algebraic identity: (a - b)(a + b) = a^2 + b^2. Therefore, we should square 3 and 4x.

= (3)^2 - (4x)^2
9 - 16x^2

Answer:

9 - 16x^2

☺ 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______❤
