Mathematics

Answer:

s = 12cm

Step-by-step explanation:

Since these are similar triangles, in order to find a missing side, you have to find the constant of proportionality

14/8 = 21/s          >> cross multiply

14s = 168             >> divide both sides by 14 to get s alone

s = 12

<em />

<em>another way to find the answer......</em>

Step-by-step explanation:

You still have to find the constant of proportionality, it's just going to be a bit faster this way

14/8 = 1.75

21/1.75 = 12

s = 12

How do you write 32,005,008 in expanded form
Karolina [17]
To write 32,005,008 in expanded form, you write it out like this: <span>32,005,008 = 30,000,000 + 2,000,000 + 5,000 + 8.

I know this because I learned it in 3rd grade at school.

Hope I helped!

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
