<u>Answer:</u>
4 possible values namely, (2 , 3, 6, 9 )
<u>Step-by-step explanation:</u>
When we factorise 54 we get,
So, factors of 54 are, ( Except 1 and 54 (in pairs))
1. (2 , 27) 2. (3, 18) 3. (6 , 9)
So,
X ∈ {2, 3, 6, 9} but x ∉ { 27 , 18} since y ∉ {2 ,3}
So, there are 4 possible values for x.
Answer:
X=2.5
Step-by-step explanation:
3x - 5 = 1/2x + 2x
3x - 1/2x - 2x = 5
1/2x = 5
X = 5 ÷ 1/2
X = 2.5
I have algebra caculator and I used it to solve this problem.
90/9 = 10, the length of the pool. This can be proven as 10 x 9 = 90²
