-5x + 46 +4z
Combine like terms
-5x + 2x = -3x
-3x + -2x = -5x
14 - (-32) = 46
4z is left alone since it doesn't have a like term.

Answer:

\large\boxed{\dfrac{x+1}{x}=1+\dfrac{1}{x}}

Step-by-step explanation:

\dfrac{x^2-1}{x^2-x}=(*)\\\\x^2-1=x^2-1^2\qquad\text{use}\ a^2-b^2=(a-b)(a+b)\\=(x-1)(x+1)\\\\x^2-x=(x)(x)-(x)(1)\qquad\text{use the distributive property}\\=x(x-1)\\\\(*)=\dfrac{(x-1)(x+1)}{x(x-1)}\qquad\text{cancel}\ (x-1)\\\\=\dfrac{x+1}{x}=\dfrac{x}{x}+\dfrac{1}{x}=1+\dfrac{1}{x}

Help plssss no links or files or i will report
ra1l [238]

Answer: 350/12

I think 29 2/12 can be also true because they didn't simplify the 2/12 to 1/6.

Step-by-step explanation:

You'll have to use the basic formula for volume is length × width × height. The sample box has the area of 23 1/3 which is found by length x width. They give you the height 1 1/4. I am assuming you will need to multiply 23 1/3 by 1 1/4. You'll get 350/12.

If it's simplify further it will be 175/6 or 29 1/6 as a mixed fraction.

Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated py
Maru [420]

Answer:

48128m^3

Step-by-step explanation:

Given data

For the building

L=64m

W= 6m

H= 36m

The volume is

V= LWH/3

V=64*64*36/3

V=147456/3

V=49152m^3

For the off-Cut

L=16m

W= 16m

H= 12m

The volume is

V= LWH/3

V=16*16*12/3

V=3072/3

V=1024m^3

Hence the volume of the truncated part/Building

= Volume of building-volume of off-cut

=49152-1024

=48128m^3
