Please help me I’ve been stuck on this question for hours, I need help and explanation please

PQ = 26.2 cm

Step-by-step explanation:

The short leg of the triangle is 14 - 9 = 5 cm

Use the pythagorean theorem to find the long leg

a² + b² = c²

a² + 5² = 14²

a² + 25 = 196

a² = 171

a = 13.076696830622021

PQ = 2 * 13.076696830622021

PQ = 26.153393661244041

Rounded

PQ = 26.2 cm

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

i just took the test, the correct answer is .. 31.5 in.
