Answer:

S = 7

Step-by-step explanation:

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

So let's start off with the equation:

[tex]5s^{2} - 101 = 144\\[/tex]

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

[tex]5s^{2} = 245[/tex]

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

[tex]s^{2} = 49\\[/tex]

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

This is 7.

Hope this helps :)

Answer:

s = ±7​

Step-by-step 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​
