Answer:
Step-by-step explanation:
What you have here is called "the difference of two squares"
Difference means subtraction and both 100x2 and 49 are perfect squares.
The factored form of 100x2-49 is
(10x+7)(10x-7)
Because 10x times 10x is 100x2 and 7 times 7 is 49
One factor has a + and
One factor has a -
It is a pattern worth memorizing!
So 10x + 7 is the factor you're looking for.
Okay. So, from the two numbers that are shown right now, x will definitely represent a positive number. What we have to do is the inverse. Basically, we'll do the inverse (opposite of division) and multiply both numbers to find x. 7.85 * 3.14 = 24.649, which rounds to 24.65 if you need to round your answer to the nearest hundredth or 24.6 if you need to round it to the nearest tenth. Or if you can just use the number as it shows up, then the real answer is 24.649
Your answer will be 406 hope this helps
