A triangle has two sides that measure 4ft and 3ft. Which could be the measure of the third side?

Nezavi [6.7K]

The measure of the third side must be less than the sum of the other two. That property is valid for all triangles.

For this question, call x the measure of the third side. So you must have

x < 4 + 3

x < 7 ft

The only option that satisfies the condition above is

option A) 5 ft.

I hope this helps. =)

F (x) =2x -4; find f (-4)

NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

$f(x)=2x-4$

To calculate f(-4), we need to substitute x in our equation above with -4:

$f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12$

Note that 2*(-4) = -8

Answer: f(-4) = -12
