Question

Solve and explain
5s^2- 101 = 144​

Answer 1

S = 7

Explanation:

Ok, so we need to find out what s is.

So let's start off with the equation:

`5s^(2) - 101 = 144\\`

So what we have to do now is add 101 on both sides:

`5s^(2) = 245`

Now we just have to isolate s and divide by 5:

`s^(2) = 49\\`

Now we just have to find the square root of 49.

This is 7.

Hope this helps :)

Answer 2

s = ±7​

Explanation:

5s^2- 101 = 144​

Add 101 to each side to get the constants on the same side

5s^2- 101+101 = 144+101

5s^2 = 245

Divide each side by 5 to isolate the variable

5s^2 /5 = 245/5

s^2 =49

Take the square root of each side

sqrt(s^2) = ±sqrt(49)

s = ±7​
