Answer:

The second and third one.

Step-by-step explanation:

If you use a calculator and do 3 x 3 x 3 x 3 x 3 it equals 243. If you do 3 x 3 x 3 x 3 it equals 81 and then you do 81 x 3 it equals 243.

I hope this helps.

Which expression is equivalent to 16 - 4x^2?

melamori03 [73]

Answer:

4(2 - x)(2 + x)

Step-by-step explanation:

16 - 4x² ← factor out 4 from each term

= 4(4 - x²) ← difference of 2 squares

= 4(2 - x)(2 + x) ← in factored form

Me ajudem com a 3º questão

Alisiya [41]

I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.

$10 = \dfrac{n(n-3)}{2}$

$20 = n^2 - 3n$

$n^2 - 3n - 20 = 0$

Answer: n² - 3n - 20 = 0

That doesn't factor so there is no integer n solution.

That means there are no polygons with 10 diagonals.

$n = \frac 1 2(3 \pm \sqrt{89})$
