2 x 2 + 3x =7
4+3x=7
4-4+3x=7-4
3x=3
x=1
The correct answer is d) 4x² - 4x + 1.
The area of a square is found by squaring the side length:
(2x-1)² = (2x-1)(2x-1) = 2x*2x - 2x*1 - 2x*1 - 1(-1) = 4x² - 2x - 2x + 1 = 4x²-4x+1
Answer:
Opposite interior angles of a rhombus are congruent (the same). All 4 of them equal up to 360
If the coefficient matrix has a pivot in each column, it means that it is shaped like this:
So, the correspondant system
will look like this:
This turn into the following system of equations:
The last equation is solvable for : we easily have
Once the value for is known, we can solve the third equation for :
(recall that is now known)
The pattern should be clear: you can use the last equation to solve for . Once it is known, the third equation involves the only variable . Once
