Answer:

False

Step-by-step explanation:

To find out if you can form a triangle from the measurements, you can compare the numbers.

If you add any combination of these number together, they need to be greater than the one you're comparing to.

3 + 5 needs to be greater than 9.

But it's not.

The other combinations work:

3 + 9 > 5

9 + 5 > 3

But since the first combination didn't work, these measurements will not form a triangle.

Hope I helped :)

(I know this answer is 3 years late but I just took the test and got it right.)

False, No Triangle can be formed with those side lengths. Here's why:
The sum of side a and side a has to be greater than side c.
a+b>c
3+5= 8
8 is not greater than 9

A figure has a vertex at (5,2). If the figure has line symmetry about the x axis, what are the coordinates of another vertex of

X axis is the ones that goes left and right

(x,y)

symetric about the x axis means that the vertical distance from the x axis is the same for 2 points that are symetric about the x axis

y is height

(x,y)
(5,2)
2 is height
distance from x axis
therefor the other point is -2
(5,-2)

the other vertex is at (5,-2)

Answer:

PQ = 3.2

Step-by-step explanation:

You must use the addition property of equality, and subtract 16 from the of the 5x, and add it to the other side.

After that, you have 5x = 16

You then divide both sides by 5.

5x/5 = 1x = x

16/5 = 3.2
