Answer:
Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase.
Step-by-step explanation:
In this question, we need to tell some things that could help to check if two polygons are scaled copy of each other or not.
Check if side lengths of one polygon have been divided by the same number to decrease the size of the shape or multiplied by the same number to increase. For example, if a rectangle has a length of 10 and a height of 8, a scaled copy would be a length of 5 and a breadth of 4.
Another example is as follows:
If a rectangle has a length of 4 and a height of 3, a scaled copy would be a length of 8 and a breadth of 6.
Answer:
12 pairs of socks
Step-by-step explanation:
74-38=36
36÷3=12
You subtract 38 from 74 to find out how much money he has left after buying the sweatshirt. You then divide that number by 3 to figure out how many pairs of socks he can buy with the money he has left.
Answer:
(y + 7i)(y - 7i)
Step-by-step explanation:
It cannot be factored using real numbers, but consider
7i × - 7i
= -49i² and i² = - 1
= 49
The factoring as a difference of squares to obtain
y² + 49 = (y + 7i)(y - 7i)
Integers are whole numbers, which van be positive and negative. Positive integers are the hole numbers greater than zero, while negative are the whole numbers smaller than zero.
The thermometer for example uses positive integers (temperature presented in degrees greater than 0 degrees Celsius: 25 <span>°C</span>, and negative integers (temperature below zero , example -15 °C) .
Let volleyball be v and let basketball be b.
v : b = 4 : 7, b = 21
v : 21 = 4 : 7
v/21 = 4/7
7*v = 4*21
v = 4*21/7
v = 4*3
v = 12
Volleyballs are 12
Hope this helps.
