What is the height of the tree
Margarita [4]

Answer:

16.5 m

Step-by-step explanation:

Hi there!

Set up a proportion (letting h = the height of the tree):

\displaystyle \frac{6 ft}{8 ft} = \frac{h}{22}

Multiply both sides by 22 to isolate <em>h</em>:

6/8 * 22 = h

h = 16.5

Therefore, the height of the tree is 16.5 m.

I hope this helps!

Given the expression: 5x^10-80x^2 Part A: Rewrite the expression by factoring out the greatest common factor
Jlenok [28]

Answer:

A) 5x²(x^(8) - 16)

B) 5x²[(x⁴ + √16) • (x² + ∜16) • (x + (8√16) • (x - (8√16))]

Step-by-step explanation:

We are given the expression;

5x^(10) - 80x²

A) Since the expression is, 5x^(10) - 80x², the greatest common factor is 5x². So we will factorize that out.

So, we have;

5x²(x^(8) - 16)

B) The complete factorization of 5x²(x^(8) - 16) will be;

5x²[(x⁴ + √16) • (x⁴ - √16)]

Now, (x⁴ - √16)] can be broken than further into;

(x² + ∜16) • (x² - ∜16)

Also, (x² - ∜16) can be broken down into;

[(x + (8√16) • (x - (8√16))

So, our complete factorization gives us;

5x²[(x⁴ + √16) • (x² + ∜16) • (x + (8√16) • (x - (8√16))]
