Problem 22
$4x^2(2x^2+x-5) - x(x^3+5x^2-3) + 17$
$4x^2(2x^2)+4x^2(x)+4x^2(-5) - x(x^3)-x(5x^2)-x(-3) + 17$
$8x^4+4x^3-20x^2 - x^4-5x^3+3x + 17$
$7x^4-x^3-20x^2+3x + 17$

So the final simplified answer to problem 22 is
$7x^4-x^3-20x^2+3x + 17$

--------------------------------

Problem 23
$-2x(x^3-6x^2+6)+4x^3-(5x^4+10x)$
$-2x(x^3)-2x(-6x^2)-2x(6)+4x^3-(5x^4)-(10x)$
$-2x^4+12x^3-12x+4x^3-5x^4-10x$
$-7x^4+16x^3-22x$

So problem 23 simplifies to
$-7x^4+16x^3-22x$

---------------------------------------------------------

Problem 24
$4b[2a^2-5(3ab-2b^2)]+29ab^2$
$4b[2a^2-5(3ab)-5(-2b^2)]+29ab^2$
$4b[2a^2-15ab+10b^2]+29ab^2$
$4b[2a^2]+4b[-15ab]+4b[10b^2]+29ab^2$
$8a^2b-60ab^2+40b^3+29ab^2$
$8a^2b-31ab^2+40b^3$

So problem 24 simplifies to
$8a^2b-31ab^2+40b^3$

-------------------------------------------------

Problem 25
$2y(6x-4x^2y)+13x^2y^2-6$
$2y(6x)+2y(-4x^2y)+13x^2y^2-6$
$12xy-8x^2y^2+13x^2y^2-6$
$12xy+5x^2y^2-6$

The final answer for problem 25 is
$12xy+5x^2y^2-6$

Help for a friend? They don't have an account so I am asking for them. Please answer fast!

sveta [45]

Answer:

A. 7*5 + 4^2 - 2^3 / 4 = 35 + 16 - 8 / 4 = 35 + 16 - 2 = 49

B. The statement of seven times five plus four squared minus 2 cubed divided by 4 is equal to 49. (or whatever your friend's teacher wants when they ask for a complete sentence).

C. PEMDAS - parentheses, exponents, multiplication, division, addition, subtraction

Note:

When remembering PEMDAS, please remember that multiplication actually isn't prioritized over division - they should be performed "simultaneously" from left to right. Same with addition and subtraction. The order is: P -> E -> MD -> AS.

3xy - ² + 4x for x = -2, y = - and = 6?

Kitty [74]

Answer:

See below

Step-by-step explanation:

Not sure what you are asking....do you want to know what y is when x = -2 and the equation = 6 ?

3 xy^2 + 4x = 6 or is that 3 xy^(-2) + 4x = 6

Could use some serious editing of your question if you are able ....
