Step-by-step explanation:
Using Pythagoras theorem
x=✓(35²-21²)=✓784=28 units
So for this, we will be simplifying √180 and √125 using the product rule of radicals (√ab = √a * √b)
Starting with √180:
Now with √125:
Now that we have our simplified radicals, our equation looks like this: 6√5 - 5√5 + √5 . Combine everything, and your answer will be 2√5.
Well, if you're following PEMDAS (Parentheses, Exponents, Multi/Div, Add/Sub), yes, first you would multiply 4x2, then since it's all adding and subtracting, you would go left to right, so if I'm right..
5-8+8-1 is the equation you'd need. So..
5-8=-3 -3+8=5-1=4. If I'm right, then 4 is your total. Hope that helped!
