Step-by-step explanation:
Given
x² + 2x
Using the method of completing the square
add ( half the coefficient of the x- term)² to x² + 2x

= (x + 1)² ← perfect square
Hello!
All the angles inside a triangle is equal to 180
To find x you can do
180 - 50 - 70 = 60
x = 60
To find y you have to find the other missing angle in the other triangle
180 - 50 - 60 = 70
A line is equal to 180°
To find y you do
180 - 60 - 70 = 50
x = 60 and y = 50
Hope this helps!

No, because let’s say for example that something cost $100.00 so you take 20% (or $20) off of the 100 and you’re left with $80.00. Well then you have your 10% off coupon so you take 10% off of 80, which is 8 dollars. So now you’re at $72.00.
But if we just took off 30% from 100 originally, you would be at $70.00
So no it wouldn’t be the same. If you wanted to check the idea yourself just use different numbers and see if they match at the end.
