Answer:
Side lengths = 15 ft²
Step-by-step explanation:
Given:
Area of square = 255 ft²
Find:
Side lengths
Computation:
Area of square = side x side
Area of square = 255 ft²
Side lengths = √Area of square
Side lengths = √255
Side lengths = 15 ft²
Answer:
x=1
Step-by-step explanation:
if it is truly 9^(x-1)=27^(x-1), then you dont really need to use the quadratic fromula.
18/5 is basically 3 3/5 as a mixed number. When you convert a fraction to a decimal, you always want the denominator to either 10, 100, or 1000 so that the number is accurate. And so you multiply the denominator by what ever number will get 10, 100 or 1000, in which in this case is 10 when you multiply by 2. Multiply the numerator(3) by 2 so that it will be the same value. You should now have 3 6/10. After that, since 6/10 is basically 60/100, take out the 100 and move the decimal unit 2 units to the left of 60. And since you still have the whole number three, your final answer will be 3.6.
The improper fraction as a mixed number is 3 2/5
3 or null, dude. im pretty sure. anything that can be divided by 9, can also be divided by 3. For ex.) 27/9 = 3 and 27/3 = 9.
you can't just throw a negative in the middle of a big number, that wouldn't make sense. so the answer is 3... pretty sure.
