Answer:
8x^3-46x^2-5x+18
Step-by-step explanation:
The volume of a rectangular prism is L*W*H where
L=length
W=width
H=height.
So we want to probably find the standard form of this multiplication because writing (4x+3)(x-6)(2x-1) is too easy.
Let's multiply (4x+3) and (x-6), then take that result and multiply it to (2x-1).
(4x+3)(x-6)
I'm going to use FOIL here.
First: 4x(x)=4x^2
Outer: 4x(-6)=-24x
Inner: 3(x)=3x
Last: 3(-6)=-18
---------------------------Add.
4x^2-21x-18
So we now have to multiply (4x^2-21x-18) and (2x-1).
We will not be able to use FOIL here because we are not doing a binomial times a binomial.
We can still use distributive property though.
(4x^2-21x-18)(2x-1)
=
4x^2(2x-1)-21x(2x-1)-18(2x-1)
=
8x^3-4x^2-42x^2+21x-36x+18
Now the like terms are actually already paired up we just need to combine them:
8x^3-46x^2-5x+18
1 pound= 16 ounces
We have 5 pounds so do:
5 x 16= 80
Now we already have 4 ounces
80 + 4= 84
So answer is
84 oz
Answer:
13/9 or 1 4/9
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
because forty is eighty percent of 50
Answer:
y=-65/9
Step-by-step explanation:
12(5+2y)=4y-(5-9y)
60+24y=4y-5+9y
60+24y=13y-5
60+24y-13y=-5
60+9y=-5
9y=-5-60
9y=-65
y=-65/9
