9 is 12% of 75 check it 9* 100 = 900 / 75 = 12
Answer:
x = 14 is an extraneous solution
Step-by-step explanation:
Divide both sides by 4.
Square both sides.
Since we squared both sides, we much check for extraneous solutions because the process of squaring both sides can introduce extraneous solutions.
Check x = 14:
16 = -16 is a false statement, so the solution we found, x = 14, is an extraneous solution.
The answer is -65, -13, -7.6, 7.6, 34, 55, 62.5
Although the negative numbers may seem larger than the positive numbers that is not the case since negative numbers are below zero.
Such as this is the case of transition from negative to positive
-5,-4,-3,-2,-1, 0,1,2,3,4,5
Answer:
E = { x l x is a perfect square <36}
And we can rewrite it taking in count the list of all the perfect squares less than 36 and we have:
1= 1*1
4= 2*2
9 = 3*3
16 =4*4
25= 5*5
And we can rewrite the set on this way:
E= {1,4,9,16,25}
Step-by-step explanation:
For this problem we have the following set:
E = { x l x is a perfect square <36}
And we can rewrite it taking in count the list of all the perfect squares less than 36 and we have:
1= 1*1
4= 2*2
9 = 3*3
16 =4*4
25= 5*5
And we can rewrite the set on this way:
E= {1,4,9,16,25}
