Answer:
B. 14 ft
Step-by-step explanation:
I calculated it logically
First, substitute -2 into each equation where there is an <span>x:
</span>(-2)2 -8<span>
</span>(-2) +6
Then multiply the -2 and the 2 in the first equation and add -2 and 6 in the second:
-4 -8
4
Lastly, subtract -4 and 8:
-12
4
Now you have you answers -12 and 4!
So f(0) is 6. We see that in the points. When you look at the x value for the function on the left, you see the point (0,6) when x is 0 y is always 6.
Square because all rectangles are squares
Since b is a variable ( unknown) we replace b with 8 since its given to us so the equation turns to 8-3-3 which we do 8-3=5-3=2
