We can start with the whole of 135, and find out 10% of that.
135/10 or 135 divided by 10= 13.5
This means that 1/10 of it is equal to 13.5, and that’s 10%. To find 20%, you want to do 13.5 x 2, and this will get you 27.
The answer is 27.
(2n+4)x(4n+7)
= 8n^2+14x+16n+28
=8n^2+30n+28
that's it :) !!
2m+3=23
2m=20
m=10
let me know in the comments if you need further explanation :)
10•4=40. 40 is the perimeter of the square. To find the perimeter of the semicircle use the circle perimeter (circumference) formula and divide that answer by two. This would be pi•10. You get 31.4. Then divide by 2 so it’s 15.7. Finally add 15.7 and 40. Hope this helps... sorry it’s such a long answer
Answer:
8
Step-by-step explanation:
Let's call the missing side as x
Base on the pythagorean theorem, we have :
17² - 15² = x²
289 - 225 = x²
x² = 64
So, x equals 8.
Hope it helps
