Incase you can’t see the picture, it says “Explain how to solve the following equation and check for extraneous solutions: x= square root of -2x+6 then out of square root +3 Please help guys
Answers
Answer:
x=3
Step-by-step explanation: too much math to put here
Answer:
x= 3 ; (x=1 is an extraneous solution)
Step-by-step explanation:
-2x+6 is under a square root, so its value must be > or equal to 0
If we solve the inequality
-2x+6 ≥ 0 we obtain
-x+3≥ 0
-x ≥ -3
x ≤ 3
now that we know the possible values of x we can proceed like this:
1) move 3 on the left side of equal and change its sign
x-3 = √-2x+6
2) square the two members of the equation
x^2 + 9 -6x = -2x+6
3) solve the equation
x^2 -4x +3 = 0
(x-3)(x-1) = 0
x = 3
x = 1
4) Check if the solution are ≤ 3 and if they make true the equation
Both solutions are ≤ 3
if x = 3
3 = √-6+6 + 3
3 = 3
true
x=1
1 = √-2+6 + 3
1 = 2+3
1 = 5 false
In conclusion we can say the 3 is a real solution, while 1 is an extraneous solution

2. (3,14 * 156,25)/2 = 245.31
3. (30 * 12.5)/2 = 187.5
4. 187.5 + 245.31 + 312.5 = 745.31
Answer:
[tex]745.45 mm^{2}[/tex]
Step-by-step explanation:
(semicircle) A1 = 245.45 mm
(rectangle) A2 = 312.5 mm
(triangle) A3 = 187.5 mm
Formula for semicircle = [tex]A = \frac{1}{2} \pi r^{2}[/tex]
[tex]\frac{1}{2}\pi 12.5^{2} = 78.13\pi = 245.45 mm[/tex]
Formula for rectangle = [tex]A = lw[/tex]
[tex]25 x 12.5 = 312.5 mm[/tex]
Formula for triangle = [tex]A = \frac{1}{2} bh[/tex]
[tex]\frac{1}{2} 30(12.5) = 187.50mm[/tex]
Now we add them all up to get our answer
[tex]245.45 + 312.5 + 187.5 =745.45mm^{2}[/tex]
