Answer:
Answer: l = 82.5
Step-by-step explanation:
11/2 x 15 = 82.5.
Extraneous solutions, is answers that we get because of squaring both sides of the radical equation, but in reality, they are not going to be the solutions of the given equation.
(√(4x+41))²=(x+5)²
4x+41=x²+10x+25
x²+6x-16=0
(x-2)(x+8)=0
x1=2 , x2=-8,
And now we must to check them by substitution into initial equation
√(4x+41)=x+5
1) x=2, √(4*2+41)=2+5, √49=7, 7=7 true
2) x=-8, √(4*(-8)+41)=-8+5, √9 =-3 false,
so an extraneous solution x=-8
Answer: Sir/Ma´am/Person, it doesnt show.
Step-by-step explanation: Im on an computer and it wont show, ive tried putting it in different tabs..nothing seems to be functional. Maybe its my computer? If it isnt, heres a heads up: it could be a unrecognized file if thats what it told you somehow before you did that? But thats all i wanted to type. Enjoy your day.
Answer:
B. x = -1 or x = 4 1/3.
Step-by-step explanation:
2|3x -5| -8 =8
2|3x -5| = 16
|3x -5| = 8
The expression in the vertical lines can be positive or negative so we have 2 equations:
3x - 5 = 8 and 3x - 5 = -8
3x - 5 = 8
3x = 13
<u>x = 13/3 or 4 1/3</u>
3x - 5 = -8
3x = -8 + 5 = -3
x = -1.
