Answer:
6k(5f+3)
Step-by-step explanation:
18k+30fk
Factor out 6.
6(3k+5fk)
Consider 3k+5fk. Factor out k.
k(3+5f)
Rewrite the complete factored expression.
6k(5f+3)
Answer: A and B are the legs and C is the hypotenuse
A
using the Cosine rule in ΔSTU
let t = SU, s = TU and u = ST, then
t² = u² + s² - (2us cos T )
substitute the appropriate values into the formula
t² = 5² + 9² - (2 × 5 × 9 × cos68° )
= 25 + 81 - 90cos68°
= 106 - 33.71 = 72.29
⇒ t =
≈ 8.5 in → A
1/5 because there are 7 numbers divisible by 5 from 1 to 35. 5,10, 15, 20,25,30,35, and out of those there are 35 cards, 7 out of 35 or 7/5 can be simplified to 1/5.
