Answer:
x = 122
Step-by-step explanation:
To convert 2.4 into a radical you have to write the equation;
2.4=√x; then you square both sides, to get x by itself, resulting in 5.8; and then you have to write; "2.4 in radical form is the square root of 5.8
Answer:
16.8km
Step-by-step explanation:
Arc length = 2πr(θ/360)
=2π(8)(120/360)
=16.7551608191
≈16.8km

Answer: H. 33</h3>
=============================================
Work Shown:
Solve 5m^2 = 45 for m to get
5m^2 = 45
m^2 = 45/5
m^2 = 9
m = sqrt(9)
m = 3
I'm making m to be positive so that way the expression 12m is not negative. Otherwise, sqrt(12m) would not be a real number result.
--------------
Plug m = 3 into the expression we want to evaluate
m^3 + sqrt(12m)
3^3 + sqrt(12*3)
27 + sqrt(36)
27 + 6

Definitely the ones (A). Since its measured in feet the tallest person should be around 6 feet which does not pass 10.
