Answer:

81 mm^2.

Step-by-step explanation:

A square has 4 equal sides so each side = 36/4 = 9 millmeters long.

The area = 9^2

= 81 mm^2.

Answer:

Area is 81 mm^2

let x be a side. so 4x=36

x =9

to find the area, multiply 9*9

=81

bennett was visiting five cities that lie on a coordinate grid at A(-2,3), B(2,7), C(7,8), D(6,3) and E(2,-1). What is the midpo

bezimeni [28]

The midpoint between A and E is (0,1)

<h3>How to determine the midpoint between A and E?</h3>

The coordinates of the cities are given as:

A(-2,3), B(2,7), C(7,8), D(6,3) and E(2,-1).

From the above, we have:

A = (-2,3)

E = (2,-1)

The midpoint between A and E is calculated using

Midpoint = 1/2 * (x1 + x2, y1 + y2)

Substitute the known values in the above equation

Midpoint = 1/2 * (-2 + 2, 3 - 1)

This gives

Midpoint = 1/2 * (0, 2)

Evaluate the product

Midpoint = (0, 1)

Hence, the midpoint between A and E is (0,1)

8y + 7y <br> in standard form

dybincka [34]

Answer:

15y

8y + 7y

first, we add the numbers which is 8+7 = 15

now we add the ys that = y+y= y ( when you add any alphabet letter the answer will be itself .)

then we add 15 + y but we can not add these but we can write it as 15y

= 15y

The average cost per unit C(x), in dollars, to produce x units of toy cars is given by C(x)=(8000)/(x−50)C(x)=(8000)/(x−50). Wha

podryga [215]

$C(x)= \frac{8000}{x-50}$

gives an average cost per unit, if we want to produce x of them.

So for example, we want to produce 500 toy cars for our store, and we need a price per unit (per 1 toy car). What we do is we calculate C(500).

So to calculate the cost of one unit when producing 1250, we calculate C(1250)

$C(1250)= \frac{8000}{1250-50}= \frac{8000}{1200}=6.67$ $ is the cost of 1 toy car.
