Step-by-step explanation:
x² - 80 = 0
Add 80
to each side: x² = 80
Square root
each side: x = √80
Look it up: x = + 8.944... (rounded)
and
x = - 8.944... (rounded).
___________________________________
Here's a cleaner solution:
x² - 80 = 0
Add 80
to each side: x² = 80
Square root
each side: x = √80
But 80 = 16 · 5
So √80 = √16 · √5
√16 = 4, so x = 4 √5
Step-by-step explanation:
An easy way to plot two points and connect them with line
<u>Point 1</u>
- x = 0, this gives us y = - 3
- So (0, - 3)
<u>Point 2</u>
- x = 3, this gives us y = 0
- So (3, 0)
Now plot these two points to get the line
Answer:
x= 11
Steps:
55= 44+x
-44 -44
(Subtract 44 on both sides)
11= x
(After subtracting 44 on both sides, the 44 on the right side of the equal sigh would be canceled and you would get the answer of 11 after subtracting 44 from 56.)
