Answer:
a= 2x <u><em>(edit: i just forgot it should be a integer x.x, forgive my blondiness)</em></u>
Step-by-step explanation:
usually when doing equations like that, you can separate one of the parenthesis with 0
(in this case, we will use (2x-a) )
Then create a equation, which should look like:
2x-a=0
Then solve for a

Answer:
1. Area of rectangular rug is 
2. Area of triangular room is 
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, rectangle and triangle.
step one
let us start by solving for the area of the rectangular rug
given data
Area A = ?
Length l = 11 ft
Width w= 10 ft
we know that the area of a rectangle is expressed as

substituting our given data we have

step two
let us solve for the area of the triangular room
given data
Area A = ?
base b = 30 ft
height h= 22 ft
we know that the area of a triangle is expressed as

substituting our given data we have

Answer:
Step-by-step explanation:
Are the volumes equal? No, so throw out the first and the last one.
Is the volume of the pyramid greater than the volume of prism?
No, so throw out the third one
so by inspection it must be the remaining one
or mathematically
vol pyramid = (1/3)(base)(height)
vol prism = (base)(height)
vol pyramid / vol prism
(1/3)(base)(height) / (base)(height) = 1/3
Answer:
-64
Step-by-step explanation:
I just simplify the like terms to make it easier visually. After that, I plugged in j and k and solve for the answer which is -64.
Use the distributive property to get... 2.4a - 0.48b + 8.4c
