A.12
B.4
C.9
D.14
is c 9
Answer:
Its a square. if you graph it, you would see.
Step-by-step explanation:
Answer:8:00
Step-by-step explanation:
You do 20+45 which =65 therefore there’s 60 min in a hour so it would be 7:00 then add the 5 mins =7:05 A.m , then you add 55+5 which =60 and add that to get 8:00
Answer:
He failed to check for extraneous solutions
Step-by-step explanation:
sqrt(x+6) -4 =x
Add 4 to each side
sqrt(x+6) -4+4 =x+4
sqrt(x+6) =x+4
Sqaure each side
(sqrt(x+6))^2 =(x+4)^2
x+6 = x^2 +8x+16
Subtract 6 from each side
x = x^2 +8x +10
Subtract x from each side
0 = x^2 +7x +10
Factor
0 = (x+5) (x+2)
Using the zero product property
x=-5 x=-2
Check the solutions
sqrt(-5+6) -4 =-5
sqrt(1) -4 = -5
1-4 =-5
-3 does not equal -5 not a solution
sqrt(-2+6) -4 =-2
sqrt(4) -4 = -2
2-4 =-2 is a solution
Answer:
x=0.3
Step-by-step explanation:
we can organize the equation in a convenient form and to simplify
now we can apply log in base 2 to get x
where we have used that
I hope this is useful for you
