Kyle put "two" rectangles together to make this shape, so cut the shape into two. Then we know the bottom of one of the rectangles which is 16 is subtracted by 8 because half of 16 is 8 and 8 is one the measurements.

Б) 3х2 – 10 = 152 how to solve with square root

Tju [1.3M]

Answer:

$3\sqrt{6}$ and $-3\sqrt{6}$

Step-by-step explanation:

We will take numbers to one side and variables to one side eliminate the "Square" with "Square Root" and solve for the variable x. The process is shown below:

$3x^2-10=152\\3x^2=152+10\\3x^2=162\\x^2=\frac{162}{3}\\x^2=54\\x=\sqrt{54}$

Now, we need to reduce the radical by using the rule shown below:

$\sqrt{x*y}=\sqrt{x} \sqrt{y}$

Now,

$\sqrt{54}=\sqrt{6*9} =\sqrt{6} \sqrt{9} =3\sqrt{6}$

The correct answer is $3\sqrt{6}$ and $-3\sqrt{6}$

Note: squaring positive and negative makes the same answer

In 1990 four towns had the same population. Since then, the population of town 1 grew by a factor of 1.02, the population of tow

Alborosie

Answer: Town 1

Step-by-step explanation:

Town 1's population is growing at a factor of 1.02 which means that it is increasing by 2% a year.

Town 2 is growing at a factor of 0.999 which means that it is decreasing at a rate of:

= 1 - 0.999

= 0.1%

Town 3's population is increasing by 150 a year and town 4 is 200 people a year.

Town 1 will eclipse them all eventually because it is growing proportionally at 2%.

Towns 3 and 4 will eventually see 150 and 200 people fall below 2% of their town's population which means they will be growing at a slower rate than Town 1.
