Answer:
27
Step-by-step explanation:
r = 9
s = 6
r^2
= r x r
= 9 x 9
= 81
13s
= 13 x 6
= 108
13s - r^2
= 108 - 81
= 27
Answer:
x = 65
Step-by-step explanation:
using the Altitude- on- Hypotenuse theorem
(leg of big Δ )² = (part of hypotenuse below it ) × (whole hypotenuse)
x² = 25 × 169 = 4225 ( take square root of both sides )
x =
= 65
answer: -5 
work:
set up as fractions.

so, multiply -2 x 8 and 1 x 3.
you get 
or, -5
