Answer:

The simplified form is

100n^2-1=(10n)^2-1^2

Step-by-step explanation:

Given the expression

100n^2-1

we have to simplify the above expression.

Expression: 100n^2-1

10^2n^2-1^2

As a^2b^2=(ab)^2

∴ 10^2n^2-1^2

⇒ (10n)^2-1^2

which is required simplified form.

Option 1 is correct

Which expression is equivalent to 100 n2 − 1? (10n)2 − (1)2 (10n2)2 − (1)2 (50n)2 − (1)2 (50n2)2 − (1)2

Regroup:
100n^2-1

=10^2n^2-1
=(10n)^2-1^2

So the correct answer is : 
(10n)^2-1^2

To attempt to factor a polynomial of four or more terms with no common factor, first rewrite it in groups. Each group may possibly be separately factored, and the resulting expression may possibly lend itself to further factorization if a greatest common factor<span> or special form is created.</span>

A company plans to build a wheelchair ramp with the following
Liono4ka [1.6K]

9514 1404 393

Answer:

  yes

Step-by-step explanation:

The height that would be allowed with a ramp 43.5 feet long is ...

  h = (43.5 ft)·sin(4.8°) ≈ 3.64 ft

The proposed height is less than 3.64 ft, so the ramp angle is less than 4.8°.

__

The ramp angle is actually arcsin(3/43.5) ≈ 3.95°, which is less than 4.8°.

15s^11-25s^4 factorised <br><br> plz tell me. :)
saveliy_v [14]

For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have

5(3s^{11}-5s^4)

As for the literal part, you can factor s^4 because it's the power of s with the smallest denominator. So, we have

5s^4(3s^7-5)
