Answer:
-3x^6 -x^4 +2x^3 -8x +8
Step-by-step explanation:
Use the distributive property 4 times.
(-3x^3 + 2x - 4)×(x^3 + x - 2)
= -3x^3(x^3 +x -2) +2x(x^3 +x -2) -4(x^3 +x -2) . . . . once
= -3x^6 -3x^4 +6x^3 +2x^4 +2x^2 -4x -4x^3 -4x +8 . . . . 3 more times
= -3x^6 +x^4(-3+2) +x^3(6 -4) +2x^2 +x(-4 -4) +8 . . . . group like terms
= -3x^6 -x^4 +2x^3 -8x +8
Answer:
Option B.) 3 inches
Step-by-step explanation:
Let us first express some principles that we can use to solve our problem. Generally, the Volume of a Box is given by:
where
: is the volume
: is the height
: is the width
: is the length
Now we know that:
Volume of Box A ( ) is Equal to Volume of Box B ( ) so we have:
So now we can find the Length ( ) of Box B easily, as we now the volume along with the height and the width, as follow:
So the Length of Box B is 3 inches, thus Option B. is correct.
Answer:
The first is 3 and the second is 18
Step-by-step explanation:
Let the first number be x and the second number be 6x
The sum of the two is 21 which means
x+6x= 21
7x=21
Divide both sides by 7
X=3
And the second number is six times the first which means
6(3)=18
Therefore,the first number is 3 and the second number is 18
