Answer:
b-2 i think. Im pretty sure its right if not sorry
Let 
be the dimensions of the rectangle. We know the equations for both area and perimeter:
So, we have the following system:
From the second equation, we can deduce
Plug this in the first equation to get
Refactor as
And solve with the usual quadratic formula to get
Both solutions are feasible, because they're both positive.
If we chose the positive solution, we have
If we choose the negative solution, we have
So, we're just swapping the role of 
and 
. The two dimensions of the rectangle are 
and 
Answer:
20
Step-by-step explanation:
N + (18 - 6) = 32
Simplify bracket
N + 12 = 32
Subtract 12 from both sides to eliminate 12 on the left side
N + 12 - 12 = 32 - 12
N = 20
A square matrix has the same number of rows as columns. In computer graphics, square matrices are used for transformations. A rectangular matrix is one where the number of rows or columns may not be the same. ... Below is a 4 x 1 column matrix. A row matrix consists of a single row.
x=0
let's solve your equation step-by-step
2(4x+3)-12=3x-6
(8x)+(6-12)=3x-6
8x-6=3x-6
subtract 3x from both sides.
8x-6-3x=3x-6-3x
5x-6+6=-6+6
5x=0
5x/5=0/5
x=0
I hope that helps you
