Find x segments of circles

Mathematics
1 answer:
DerKrebs [107]3 years ago
7 0

Answer:

x = -9

x = 2

Step-by-step explanation:

We can say that:

x (x + 7) = 6*3

x² + 7x = 18

x² + 7x - 18 = 0

Now solving by quadratic formula we get;

x = 2, and -9

if we substitute in -9 for x, let's see what happens:

(-9) (-9 + 7) = 6*3

(-9) (-2) = 6*3

18 = 18

therefore x = -9 works! Let's see what happens if we substitute x in for 2;

(2) (2 + 7) = 6*3

(2) (9) = 6*3

18 = 18

Therefore x = 2 works as well!

<u>The final answer would be;</u>

<u>x = -9</u>

<u>x = 2</u>

Hope this helps!

During two years, the population of birds of an island became 7 times more than before. If the first year increase in the popula
nordsb [41]

Answer:

The percent increase of the second year is 400%.

Step-by-step explanation:

Consider the provided information.

Let the population of birds was x.

After 2 years the population becomes 7 times more than before.

Therefore, after 2 years population is 7x.

In first year increase in the population was 40%.

Population after 1st year = x + 40% of x

Population after 1st year = x + 0.40x

Population after 1st year = 1.4x

The population increase from 1st year to 2nd year is: 7x-1.4x=5.6x

Thus the percentage increase is:

\% increase=\frac{5.6x}{1.4x}\times100=400\%

Hence, in second year the population of birds increase by 400%.
