£36.48.
1. Multiply 38 by 0.04 (4% in decimal) and you’ll get 1.52
2. Subtract 1.52 from 38 to get 36.48
65+70=135
180-135=45
(x+2)=45
x=43
Answer:
![x=25](https://tex.z-dn.net/?f=x%3D25)
Step-by-step explanation:
we know that
In this problem
The value of x represent the radius of the circle
so
Applying the Pythagoras theorem in the right triangle of the figure, you can find the radius of the circle O
see the attached figure to better understand the problem
![x^{2} =20^{2}+15^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D20%5E%7B2%7D%2B15%5E%7B2%7D)
![x^{2} =400+225](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D400%2B225)
![x^{2} =625](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D625)
square root both sides
![x=25](https://tex.z-dn.net/?f=x%3D25)
Answer:
B
Step-by-step explanation:
Hey There!
To solve this problem we have to combine like terms
![7x^3-6x^3=x^3\\6x^2-8x^2=-2x^2\\-5x+10x=5x\\5-7=-2](https://tex.z-dn.net/?f=7x%5E3-6x%5E3%3Dx%5E3%5C%5C6x%5E2-8x%5E2%3D-2x%5E2%5C%5C-5x%2B10x%3D5x%5C%5C5-7%3D-2)
So our answer would be
(b)
Answer:
5 x 2
Step-by-step explanation:
