Step-by-step explanation:
<em>Look at the picture.</em>
Any pair of choice can be the coordinates of the rotation of the point
W (-3, 4) clockwise.
All points have the same distance from the beginning.
The formula of a distance between the origin and a point (x, y):
![d=\sqrt{x^2+y^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7Bx%5E2%2By%5E2%7D)
W(-3, 4)
![d=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-3%29%5E2%2B4%5E2%7D%3D%5Csqrt%7B9%2B16%7D%3D%5Csqrt%7B25%7D%3D5)

Answer:
12(3+1)
Step-by-step explanation:
use distributive property to solve
13 times 3 is 36
12 times 1 is 12
so 12(3+1) is equal to 36+12
have a good day :)
Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.
<u>Numerical Expression</u>
"Difference" indicates that we'll be subtracting 13 from 48.
48 - 13 = 35
<u>Algebraic Expression</u>
Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.
48 - 13 = d
35 = d
