I only know the answer to the first question which is 5.
Answer:
2
Step-by-step explanation:
this one is correct
1/5+1/5=2/5
The extraneous solution of startroot 4 x 41 endroot = x 5 will be A. -8.
<h3>What is an extraneous solution?</h3>
It should be noted that an extraneous solution simply means a root of a transformed equation which isn't part of the original equation.
✓4x + 41 = x + 5
Square both sides
4x + 41 = x² + 10x + 25
x² + 6x - 16
x(x + 8) - 2(x + 8) = 0
x + 8 = 0
x= 0 + 8 = 8

Answer: No, the ratios 11/15 and 1/6 do not form a proportion.
Explanation: Proportion says that two ratios (or fractions) are equal.
Example:
Proportion 1/3 : 2/6
So 1-out-of-3 is equal to 2-out-of-6
The ratios are the same, so they are in proportion.
If I multiplied 1 by 11 and then 6 by 11, I would get 11/66, therefore 11/15 and 1/6 do not form a proportion.
