Which solution to the equation StartFraction 1 Over x minus 1 EndFraction = StartFraction x minus 2 Over 2 x squared minus 2 EndFraction is extraneous? x = 1 and x = –4 neither x = 1 or x = –4 x = 1 x = –4

x = - 4

Step-by-step explanation:

Given the expression

This can also be expressed as;

Cross multiply

Add 2 to both sides

Hence the required extraneous solution is x = -4

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
