Answer:
12.4+3√7 is irrational
Step-by-step explanation:
12.4 is a rational number
3√7 is an irrational number
<u>The sum of a rational number and an irrational number is irrational.</u>
So, 12.4+3√7 is irrational
The solution has to be a value of x. Since you already have x, you just have to plug in the value and see what fits. In this case thats the third from the top:
5^2 - 10*5 + 25 = 0
25 - 50 + 25 = 0
0 = 0
Hope it helps!
this is false
(6+8)^2= 196
6^2+8^2=100
They are not equal so this is a false statement
