Which statements describe the figure on the grid if each square has side lengths of 1 cm? Check all that apply. On a coordinate

PolarNik [594]

The figure on the grid is an illustration of areas and perimeters of a shape

<h3>How to determine the true statements?</h3>

The question is incomplete, as the figure is not given.

So, I will provide a general explanation on how to determine the area and the perimeter of a shape.

The area of a shape is the amount of space on that shape.

Take for instance a square that has a side length 5 units.

The area of the square would be:

Area = 5 * 5 = 25 square units

On the other hand, the perimeter is the sum of the side lengths of the shape.

Using the same square that has a side length 5 units.

The perimeter of the square would be:

Perimeter = 4 * 5 = 20 units

What is x if n≠m? Please help!

lorasvet [3.4K]

Answer: $x = \frac{mn(q - p)}{n-m}\\\\$

================================================

Work Shown:

Part 1

$\frac{x-m}{m} + p = \frac{x-n}{n} + q\\\\\frac{x-m}{m} - \frac{x-n}{n} = q - p\\\\\frac{n(x-m)}{mn} - \frac{m(x-n)}{mn} = q - p\\\\\frac{xn-mn}{mn} - \frac{xm-mn}{mn} = q - p\\\\\frac{xn-mn-(xm-mn)}{mn} = q - p\\\\$

Part 2

$\frac{xn-mn-xm+mn}{mn} = q - p\\\\\frac{xn-xm}{mn} = q - p\\\\\frac{x(n-m)}{mn} = q - p\\\\x(n-m) = mn(q - p)\\\\x = \frac{mn(q - p)}{n-m} \\\\$

-------------------------------

Explanations:

There are quite a bit of steps. I decided to break things into two parts.
The goal is to get x all by itself on its own side, which is why I subtracted (x-n)/n from both sides in part 1, step 2. I also subtracted p from both sides.
Afterward, I gave each fraction the LCD mn. I multiplied top and bottom of the first fraction by n/n. I did a similar operation to the second fraction, but with m instead.
From there, we distribute and simplify. The mn terms cancel on the left side numerator (second step of part 2).
The n≠m is there to prevent the denominator (n-m) from being zero. We cannot divide by zero.

Please include work! :)

UNO [17]

Answer:

m = 13.

Step-by-step explanation:

Recall that adding logarithmic equations, (ex: log a + log b) is the same as log (a·b). Therefore:

log 12 + log 5 = log (4m + 8)

log (12·5) = log (4m + 8)

log (60) = log (4m + 8) **Ignore 'Log' to solve for 'm'

60 = 4m + 8 **Subtract both sides by 8

52 = 4m **Divide both sides by 4

m = 13.

he given table shows the growth of Anytown, NC by providing the estimated population from 1970 to 2000. Year Population 1970 4,8

Morgarella [4.7K]

The population is increasing by 1500 each year and starts at 1970 population ( = 4800) so the equation is
y=1500x+4800
