Answer:
5.84
Step-by-step explanation:
She has two shirts and their 23.99 each
23.99 x 2 = 47.98
Then she has a pair shoes that cost 41.99
Add
47.98 + 41.99 = 89.97
6.5% = 0.065
89.97 x 0.065 = 5.84
the second one I believe
-6+p=-22
add 6 to each side
+6 -6+p=-22+6
p = -16
Yes it is. Input the numbers into the pythagorean theorem,
and if they equal each other it is a right triangle.
