Answer:
16y-4x
Step-by-step explanation:
first distribute the negative to the numbers in parentheses
13y-5x+3y+x
then combine like terms
13y+3y=16y
-5x+x=-4x
16y-4x
Answer:
7.31 x 10^-2
Step-by-step explanation:
scientific notation multiplies a number between 1 and 10 by a power of ten
Answer:
480
Step-by-step explanation:
We will use the order of PEMDAS. First, everything in parenthesis must be completed. Since 6x4 is in parenthesis, we multiply it and get 24.
Since we now have 20(24). We can multiply them by each other.
A trick to do this manually is to notice that 20 is 10 x 2, meaning that in reality this equation is 10 x 2 x 24. Multiply 2 x 24 = 48, and 48 x 10 = 480.
Answer:
wheres the diagram?
Step-by-step explanation:
need the diagram in order to answer the problem
Let x,y be two different numbers
suppose x^2=y^2
then x^2-y^2=0
which yields (x+y)(x-y)=0
so either x=y or x=-y
In any case, x and y must be the same value
also when a vairable is squared like y=x^2
we must note that there are 2 possible solutions
x=(+/-)sqrt(y)
