3y+11 plus 7x-30 plus 5x+14 find x and the y

Viktor [21]

3y + 11 + 7x - 30 + 5x + 14

3y + 12x - 5

3y = -12x + 5

y = (-12x + 5)/3
x = (3y - 5)/-12

Does anyone have the answers for the rest of this or know the answers ?

Answer:

a) $4x^4-4x^3-16x^2+16x$

b) $4x^4-4x^3-16x^2+16x$

5. Yes

Step-by-step explanation:

The distributive property is:

$(a+b)(c+d)=ac+ad+bc+bd$

It can be extended to a lot of terms as well.

We will use this to multiply both of the probelms shown.

4 a)

$(4x^2-4x)(x^2-4)=(4x^2)(x^2)-(4)(4x^2)-(4x)(x^2)+(4x)(4)=4x^4-16x^2-4x^3+16x=4x^4-4x^3-16x^2+16x$

The answer is $4x^4-4x^3-16x^2+16x$

4 b)

$(x^2+x-2)(4x^2-8x)=(x^2)(4x^2)-(8x)(x^2)+(x)(4x^2)-(8x)(x)-(2)(4x^2)+(2)(8x)=4x^4-8x^3+4x^3-8x^2-8x^2+16x=4x^4-4x^3-16x^2+16x$

The answer is $4x^4-4x^3-16x^2+16x$

5. Yes

Answer:

(a) 2021

Step-by-step explanation:

The expression can be simplified.

$\displaystyle\frac{a^4+b^4+2a^2b^2+a^3b+ab^3}{a^2+b^2}+ab=\frac{(a^2+b^2)^2+ab(a^2+b^2)}{a^2+b^2}+ab\\\\=a^2+b^2+ab+ab=(a+b)^2\\\\=(\sqrt{2021})^2=\boxed{2021}$
