1 answer:

8 0

5-2(y+1)=21

Distribute
5-2y-2= 21

Combine like terms
3-2y=21

Subtract 3 from both sides
-2y= 18

Divide both sides by -2
y= -9

Final answer: y=-9

What is the sum of StartRoot negative 2 EndRoot and StartRoot negative 18 EndRoot?

Darya [45]

Answer:

$4 \sqrt{2} i$

Step-by-step explanation:

We want to find the sum of

$\sqrt{ - 2} + \sqrt{ - 18}$

We can rewrite this as

$\sqrt{ 2 \times - 1} + \sqrt{ 18 \times - 1}$

This becomes;

$\sqrt{2} \times \sqrt{ - 1} + \sqrt{18} \times \sqrt{ - 1}$

Recall that;

$i = \sqrt{ - 1}$

This implies that;

$\sqrt{2} i + 3 \sqrt{2} i$

Combine like terms:

$4 \sqrt{2} i$

Answer:

40°

Step-by-step explanation:

Measure of Nonagon (9-sided polygon) = 1260°

Each angle measure = 1260 ÷ 9 = 140°

The value of x (the outside angle) = 180° - 140° = 40°
