Answer:
27x-6
Step-by-step explanation:
To distribute 6(3x-1) properly, 6 needs to be multiplied with 3x and -1.
6*(-1)=-6,
3x*6=18x.
Without simplifying, the answer we get from this is 18x+9x-6. 18x+9x=27x, so the algebraic expression equivalent to 6(3x-1)+9x is 27x-6.

Step-by-step explanation:
To complete the square
add ( half the coefficient of the x- term )² to x² - 2x
x² + 2(- 1)x + 1
(x² - 2x + 1 = (x - 1)²
Answer:
48
Step-by-step explanation:
You can use a graphing calculator like desmos or draw your own graph to figure this out. Start by graphing each of those points. Then count the width and height. Multiply them to get the area. The width and height of the rectangle were 6 and 8, so the area is 48
