it can be used to calculate the length of a circular bracelet
Answer:
20
Step-by-step explanation:
25 + 7x = 165
25 + 7(20) = 165
25 + 140 = 165
give me for free and il solve it take 20 min for me to solve
-3√45 + 3√20 = -3√(9 · 5) + 3√(4 · 5) =
= -3√(3² · 5) + 3√(2² · 5) =
= -3 · 3√5 + 3 · 2√5 =
= -9√5 + 6√5 = -3√5 ← the end
Answer:
In simplest form, it should be:
3:2
6 / 2 = 3
4 / 2 = 2
Hope this helps!
