1 answer:

3 0

-4(8-(-3))+7

Remove the parentheses, negative with negative will equal a positive so the new equation will be -4(8+3)+7. So 8+3=11, -4(11)+7. -4(11)=-44 and then add -44+7 which will equal -37

Simplify the difference. (–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x)

sineoko [7]

Answer: $2x^4+2x+10$

Step-by-step explanation:

You need to remember the mulplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

Knowing this, you can distributive the negative sign. Then you get:

$(-7x- 5x^4 + 5) - (-7x^4 - 5 - 9x)=-7x- 5x^4 + 5 +7x^4 + 5 + 9x$

Now you need to add the like terms. Then:

$=2x+2x^4+10$

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

$=2x^4+2x+10$
