Simplify the following:
x^3 - 2 x^3 + x - 3 x - 5 - 4
Grouping like terms, x^3 - 2 x^3 + x - 3 x - 5 - 4 = (-2 x^3 + x^3) + (x - 3 x) + (-5 - 4):
(-2 x^3 + x^3) + (x - 3 x) + (-5 - 4)
x^3 - 2 x^3 = -x^3:
-x^3 + (x - 3 x) + (-5 - 4)
x - 3 x = -2 x:
-x^3 + -2 x + (-5 - 4)
-5 - 4 = -9:
-x^3 - 2 x + -9
Factor -1 out of -x^3 - 2 x - 9:
Answer: -(x^3 + 2 x + 9)
___________________________________________________________
Yes = (-2x^3 + x - 5)+( x^3 - 3x - 4) = ( x^3 - 3x - 4)+(-2x^3 + x - 5) = True
Proof:

Right Side.
Simplify the following:
x^3 - 2 x^3 + x - 3 x - 5 - 4
Grouping like terms, x^3 - 2 x^3 + x - 3 x - 5 - 4 = (x^3 - 2 x^3) + (-3 x + x) + (-4 - 5):
(x^3 - 2 x^3) + (-3 x + x) + (-4 - 5)
x^3 - 2 x^3 = -x^3:
-x^3 + (-3 x + x) + (-4 - 5)
x - 3 x = -2 x:
-x^3 + -2 x + (-4 - 5)
-4 - 5 = -9:
-x^3 - 2 x + -9

Answer:
7 ( 3x + 5y) = <u>21x+35y</u>
<u>Step-by-step explanation:</u>
<u>Step 1 : </u> apply the distributive law. <u>("the law relating the operations of multiplication and addition")</u>
<em>a ( b + c ) = ab + ac</em>
7 ( 3x + 5y) = 7 x 3x + 7 x 5y
<u>Step 2 : simplify </u>7 x 3x + 7 x 5y
So, the answer is <u>21x+35y</u>
