42 less than x is -50 would be written as x - 42 = -50
Answer:
6n²√3
Step-by-step explanation:
2√3n•√9n³
The above expression can be simplified as follow:
Recall
√9 = 3
2√3n•√9n³ = 2√3n × 3√n³
Recall
m√a × n√b = mn√(a × b)
Thus,
2√3n × 3√n³ = (2×3) √(3n × n³)
2√3n × 3√n³ = 6√3n⁴
Recall:
√aᵇ = (aᵇ)¹/² = aᵇ/²
√n⁴ = n⁴/²
√n⁴ = n²
Thus,
6√3n⁴ = 6n²√3
Therefore,
2√3n•√9n³ = 6n²√3
Answer:
a= 2

Answer:
The circumference is around 785 feet
Step-by-step explanation:
The circumference of a circle is pi x radius x 2 or pi x diameter.
If the Ferris wheel's radius is 125, then this is what you do:
pi x 125 x 2
= pi x 250
= 3.14 x 250
= 785

Answer:
5feet per year
Step-by-step explanation:
We need to find the distance it grew in that 7 1/2 years:
63 - 25 1/2 = 37 1/2
Now to find the average yearly growth we can divide this by 7 1/2:
37.5 ÷ 7.5 = 5
So the yearly rate of growth of the tree is 5f/y
