27
Step-by-step explanation:
9(4)-9= 27
Answer: x = -1
Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.
So we have 4 times 5x which is 20x and 4 times 30 which is 120.
So our equation now reads 20x + 120 = 100.
Solving from here, we subtract 120 from both sides of the equation and we have 20x = -20 and dividing both sides by 20, we find that <em>x = -1</em>.
So evens would be 2, 4,6 so p of getting an even number would be 3/6=1/2= 50%
Let's say side length is s.
s*s = 500, so s = √500.
4 sides needed, total length thus 4*s.
4√500 ≈ 89.4
