Answer:

1 and 1/3

Step-by-step explanation:

3a² -4a +1 = 0

3a²- 3a - a+ 1= 0

3a(a-1) - (a-1)= 0

(a-1)(3a -1)= 0

a-1= 0 ⇒ a= 1

3a - 1= 0 ⇒ 3a= 1 ⇒ a= 1/3

$z_1=4+2i\\z_2=-1+2i\\\overline(z_2)=\sqrt{(-1)^2+(2i)^2}=\sqrt{1-4}=i\sqrt{3}\\ z_1+\overline(z_1)=4+2i+\sqrt{4^2+(2i)^2}=4+2i+\sqrt{16-4}=4+\sqrt{12}+2i\\z_2+\overline(z_2)=-1+2i+\sqrt{(-1)^2+(2i)^2}=-1+2i+\sqrt{1-4}=-1+(2+\sqrt{3})i$

What is 3 1/2 multiplied by 2 1/4 as a mixed number or fraction

Nataly [62]

Hey there!

$3\frac{1}{2}$ × $2\frac{1}{4}$

$3\frac{1}{2}$ = $\frac{7}{2}$

$2\frac{1}{4}$ = $\frac{9}{4}$

$\frac{7}{2}$ × $\frac{9}{4}$

$7\times9 = 63$

$2\times4 = 8$

$\boxed{Answer: \frac{63}{8} ; 7\frac{7}{8} }$

Good luck on your assignment and enjoy your day!
