2⃣, -4⃣ = x; no radical necessary.
B. 3 √3
The shortcuts for a 30 60 90 triangle is that the:
Hypotenuse is 2 times the short leg
The long leg is √3 times the short leg.
Making it 3 √3
Another way is by the Pythagorean Theorem.
a^2+b^2=c^2
3^2+b^2=6^2
9+b^2=36
Subtract 9 from both sides
b^2=27
Square root both sides
b=5.2 or the √27
√27 can be simplified more
An equation that equals to 27 that has a perfect square is 9*3
√9* √3
The perfect square of 9 equals to 3
So 3 √3
B = 100(1 + 0.04)^12 = 100(1.04)^12 = 100(1.601) = $160.10
Writing it as a decimal would be 3.85 you just divide it
Answer:
21n
Step-by-step explanation:
1. triple n = 3(n)
3n
3. multiply 7 = 7(3n) = 21n
