Answer:
<u>Options B and D</u>
Step-by-step explanation:
6x² + x - 1 = 0
6x² + 3x - 2x - 1 = 0
3x(2x + 1) - 1(2x + 1) = 0
(3x - 1)(2x + 1)
x = 1/3 and -1/2
<u>Options B and D</u>
Answer:
I would say C.
Step-by-step explanation:
Point A would be exactly at sea level while B and C are both under A
(sea level).
Let's find X. Since both equations are equal to y, they are equal to themselves.
-3x-3=-3; we just need to solve from here. -3x-3=-3; let's add 3 to both sides. -3x=0; this means that 0 is X.
Let's use a graph to check.
So, y is -3.
So, (0, -3) is when the two lines intersect and it's our solution.
Answer:
Area= 480 because 8x6x10=480
Perimeter= 24 because 8+6+10=24
