Answer:
f(-4) = 56
Step-by-step explanation:
f(x) = 3x² - 2x
To find f(-4), substitute -4 for all the values of x in f(x).
f(-4) = 3(-4)² - 2(-4)
Square -4.
f(-4) = 3(16) - 2(-4)
Multiply 3 and 16.
f(-4) = 48 - 2(-4)
Multiply -2 and -4.
48 + 8
Add.
56
You had the right idea! :)
I'm sure this is the answer

Answer:
<em>10 feet</em>
Step-by-step explanation:
here's the reason ; -
let's take the missing side be x
we know, the one side of a triangle should always be greater than the difference between the other two sides, so ,
=》x > 7-4
=》x > 3
and the measure of a side should always be less than the some of the other two sides, hence
=》7 + 4 > x
=》11 > x
now, we have : -
11 > x > 3
value of x should be more than 3 and less than 11 , hence 2 ft , 3 ft and 12 ft can't be the measure of third side,
so, we got our third side as 10 ft
