Answer:
Step-by-step explanation:
Since we have an x under that radical, we have to get it out from under there. To do that, do the opposite of the square root, which is to square. But because this is an equation, you have to do the same thing to both sides. Doing this gives you
Get everything on one side and set the quadratic equal to 0 and solve for x:
Factor this into 2 factors of (x - 3)(x - 3) = 0. As you can see they are both the same, so x - 3 = 0 and x = 3. That's your answer. x = 3.
If we write 4 to each side of 10, we will get a four digit number 4104, which is a multiple of 72.
To find out other possible solutions, first start with 1 in front of 10.
Now, divide 110 by 72.
The remainder is 38.
We are going to put one more digit after 10.
So, let us check if there is any three digit number whose first two digits are 38 and which is a multiple of 72.
There is no such number since 5 × 72 = 360 and 6 × 72 = 432.
So, there is no four digit number whose first three digits are 110 and which is a multiple of 72.
If we try like this, we can find 4104 is the only solution.
12 hours, if you multiply 50 by 12 it will give you 600 and add the 400
