Answer:

Step-by-step explanation:

Additive identity is a property that involves the sum of two or more integers in an equation without compromising the equality of the equation.

Given the equation

(5+2)+n = 7+n

We can see that the right hand side of the equation is derived from the left hand had by addition of the values in parenthesis.

Given the right hand side;

= 5+2+n

= (5+2)+n

adding the expression in parenthesis will give;

= 7 + n

Since we added the expression in parenthesis to arrive at the expression at the right hand side, hence additive identity was used in the calculation.

Find the midpoint of the segment whose endpoints are (8,6) and (-2,-8).

inna [77]

Answer:

$\huge{ \fbox{ \sf{ \: ( \: 3 \: , \: - 1 \: )}}}$

Step-by-step explanation:

$\star{ \sf { \: Let \: the \: points \:be \: A \: and \: B}}$

$\star{ \sf{ \: Let \: \: A (8,6) \: be \: (x1 \:, y1) and \: B(-2,-8) \: be \: (x2 \:, y2)}}$

$\underline{ \sf{Finding \: the \: midpoint}}$

$\boxed{ \rm{Midpoint \: = \: ( \frac{x1 + x2}{2} \: , \: \frac{y1 + y2}{2} )}}$

$\mapsto{ \sf{Midpoint = ( \frac{8 + ( - 2)}{2} \: , \: \frac{6 + ( - 8)}{2} )}}$

$\mapsto { \sf{Midpoint = ( \frac{8 - 2}{2} \: , \: \frac{6 - 8}{2} }})$

$\mapsto{ \sf{Midpoint = ( \frac{6}{2} \: , \: \frac{ - 2}{2}) }}$

$\mapsto{ \sf{Midpoint = (3 \: \: , - 1)}}$

Can somebody please solve this? It's a coordinate thingy

statuscvo [17]

Answer:

Coordinates involve two points. (x,y)

Too find a pair (coordinate), use the x and y lines on the graph and see where the point falls.

For example

Point A is number 1 on the y axis

number -4 on the x axis

So, you would write the coordinate out at 

(-4,1)

The y axis values are the second point, so after you plot all of letters, use the y axis numbers and number them from least to greatest so you can find the mystery word.

A square park is 75 m long. Find the area of the park.

Inga [223]

5625 m^2

If is is square, all sides must be congruent (all sides are 75m). To find area, you multiply width x length (how long). Therefore:

75m x 75m = 5626 m^2
