Question

Mathematics
1 answer:
tester [92]2 years ago
6 0

Answer:

Ø.

Step-by-step explanation:

Given the equation 7x^2 = -14. We are to find the value of x;

7x^2 = -14.

Divide both sides by 7

7x^2/7 = -14/7

x² = -2

Square root both sides

√x² = ±√-2

x = ±√2 i

The value of x is (-√2 i, √2 i)

Since there values is a complex values, hence there is no real solution. The answer is Ø.

Kaylis [27]

The measure of angle bcd of the polygon abcd is 40°.

Hence, option b) 40° is the correct answer.

<h3>What is a polygon?</h3>

A polygon is simply a two-dimensional a plane shape enclosed by line segments called sides.

The sum of the exterior angles of a regular polygon will always equal 360

Given that;

  • Exterior angle a = 25 degrees
  • Exterior angle b =  146 degrees
  • Exterior angle d = 149 degrees
  • Exterior angle c = ?

25° + 146° + 149° + c = 360°

320° + c = 360°

c = 360° - 320°

c = 40°

The measure of angle bcd of the polygon abcd is 40°.

Hence, option b) 40° is the correct answer.

The amount $180.00 is what percent greater than $135.00?
svp [43]
It would be: 180/135 * 100 = 36/27 * 100
= 4/3 * 100
= 400/3 = 133.33

It means, 180 is 133.33% of 135. So, the difference would be: 133.33 - 100 = 33.33%

In short, Your Final Answer would be 33.33%

Hope this helps!
