Two sides of a triangle are: 5, 14.
By triangle inequality the sum of each pair of sides must be > the third side.
x + 5 > 14
Subtract 5 from both sides.
x > 9

x + 14 > 5
Subtract 14 from both sides.
x > -9

5 + 14 > x
19 > x

x has to be greater than 9 but less than 19.

I guess you mean 5m and 14m are the lengths of 2 sides of the triangle.

If the length of any side is equal or greater than the sum of the other 2 sides then you can;t make a triangle.

So for example 19 cannot the answer because 19 = 5 + 14 . No triangle can be formed with sides that measure.
and 38 is greater than 14 + 5 so its cant be C.

The answer is A

Line segment GT contains the point G(−3, 5) and a midpoint at A(1, −4). What is the location of endpoint T?

algol [13]

Imagine you're moving along the segment. Since the midpoint is in the middle of the segment (obviously), it means that when you've traveled from G to A, you're halfway through your journey, along both x and y directions. So, let's break the problem in two and analyze both directions.

Along the x axis, you've moved from -3 to 1, so you moved 4 units forward. This means that you have 4 units still to go, and your journey will end at coordinate 5.

Similarly, along the y axis, you've moved from 5 to -4, so you moved 9 units downward. This means that you have 9 units still to go, and your journey will end at coordinate -13.

So, the coordinates of the endpoint are $T = (5,-13)$

If you prefer a more analyitical approach, simply write the definition of the midpoint and solve it for the coordinates of T.

We have $G = (-3, 5)$ and $T = (x_T,y_T)$ . The midpoint is computed as

$A = \left( \frac{-3+x_T}{2},\frac{5+y_T}{2} \right) = (1, -4)$

So, you have the equations

$\frac{-3+x_T}{2} = 1,\qquad \frac{5+y_T}{2} = -4$

Multply both equations by 2 to get

$-3+x_T = 2,\qquad 5+y_T = -8$

Move the constants to the right hand sides to get

$x_T = 5,\qquad y_T = -13$

Is 11p-7q polynomial

REY [17]

Answer: Yes; this is polynomial.

Specifically, it is a "polynomial EXPRESSION" ; but not a "polynomial equation" ; because it is not an "equation.

There are more than one variables/variable expressions, so it is a polynomial.
