Answer:

not necessarily

Step-by-step explanation:

Taking the square root of both sides, you have ...

±a = ±b

Those four cases resolve to two unique cases:

a = ±b

The given equation will be true if a = b or if a = -b. If a and b are constrained to have the same sign, then a=b is the only solution.

I need to find X but I don't know how to do it

klio [65]

I think i am doing this right i am not sure. First you need to add up all the sides (100+38+22+15) it would equal 175 then you need to subtract it from 360 and get the missing value (x) then the answer would be 185

Place the correct symbol, < or >, between the two numbers 11/18 17/24

evablogger [386]

For this case we must indicate the correct sign between the following numbers:

$\frac {11} {18}\ and\ \frac {17} {24}$

We have to:

$\frac {11} {18} = 0.611111111111\\\frac {17} {24} = 0.708333333333$

So, we have to $\frac {17} {24}> \frac {11} {18}$

Answer:

$\frac {17} {24}> \frac {11} {18}$
