X + 4 = 3x - 8
x + 12 = 3x
12 = 2x
x = 6 = AC

Harry worked 7 hours last week this is one third as many hours as Aiden work how many hours did Aiden work

Eduardwww [97]

21 hrs. Because if Harry worked one third the hrs thats Aiden worked then 7×3 =21 and 21÷3=7. So 7 is one third of 21.

I need you to explain your answer, please.

Answer:

7√6 - 5√7

Step-by-step explanation:

5√7 + 12√6 - 10√7 - 5√6 (rearranging)

= (5√7 - 10√7) + (12√6 - 5√6) (factor out √6 and √7 respectively)

= (5 - 10) √7 + (12 - 5)√6

= -5√7 + 7√6 (rearrange)

= 7√6 - 5√7

abruzzese [7]

If z ⁷ = 128i, then there are 7 complex numbers z that satisfy this equation.

$z^7 = 128i = 2^7i = 2^7e^{i\frac\pi2}$

$\implies z=\sqrt[7]{2^7} e^{i\frac17\left(\frac\pi2+2n\pi\right)}$

(where n = 0, 1, 2, …, 6)

$\implies z = 2 e^{i\left(\frac\pi{14}+\frac{2n\pi}7\right)}$

$\displaystyle\implies z = 2 \left(\cos\left(\frac\pi{14}+\frac{2n\pi}7\right)+i\sin\left(\frac\pi{14}+\frac{2n\pi}7\right)\right)$
