The sum of all possible values of b is 0 + 1 + 2 = 3.

When ever I did it I got the same answers as you did and I cant really see if they are correct this is for school so we will see if they are correct tomorrow when I turn it in.

Sorry...

10x²  sqrt ( 3x³ )

= sqrt  (10x²)² * 3x³)

=\(\sqrt{300x^7}\)

THX for  that  nice answer, BF !!!

I don't think I've seen you before....so....WELCOME ABOARD  !!!!

OK!!!!.......check  my  answers....I did this rather hurriedly  and  the pic  was a little  hard to see....

No prob  !!!

Thank you!

Angle  m  = 30

Angle  p  =   180  - 30  - (180 - 112)   = 82°

Angle   q   =    180  -  82  -  70   = 28°

Angle  n  = 50

Angle  t   =   50  +  (180 -112)   = 118°

The  angle  supplementary to angle s  =  540  - [  112   +  (180  - 82)   + (180 - 70) + 118 ]   = 102

So

Angle s  =  180  - 102  =  78° 

Angle r  = 180  -  70  - 78  = 32°

To figure  angle  u

180 -  [ (180 - 118)  +   78 ]  =  40

So

Angle  u  =   90  - 40   =  50°

Thank you!!

that's right thank you!!

The expected number of checkers is 11/2.

A+B=75

A+C=61

C*1.6666=B

A=61-C

A=75-C*1.666666

61-C=75-C*1.6666

C=21

C=21

B=35

A=40

There are 40 students in Class A

Angle bisector theorem

56/xb = 14/ax          note that xb = 50 -ax   sub that in

56 / (50 - ax) = 14/ax

56 ax = 14 (50 - ax)

70 ax = 700

ax = 10

A+B=75

A+C=61

C*1.6666=B

A=61-C

A=75-C*1.666666

61-C=75-C*1.6666

C=21

B=35

A=40

(x + 4) / (5x - 4) = 1/3

x = 8

5x - 4 = 36

Jann had 36 books.

\(\sqrt[3]{432x}\)                 this is    cubrt ( 6³ *2 x)    by moving the 6 into the radical

I THINK:

Any digit repeated    4 x 4 x 4 x 4 =  256   four-digit numbers possible

No repeats    4 x 3 x 2 x 1     = 24          256 -24 = 232 with repeats

232/256 = 29/32   

Ok ok I'll stop answering question I dont have a clue about but I'm still going to be answering more than 1 problem a day

2/5 z  = 12 + 2/3 l    or

   z = 5/2 (12 + 2/3 l)           given

z-50 = l + 50        sub in the red equation

5/2 ( 12 + 2/3 l ) = l + 50

30 + 10/6 l   -50  = l +50

-70   = - 4/6 l

l = $ 105 originally

The sum of all x is 17.

sinB = CD/BC

sinB = √65 / 9

Divisors  of 144

Divisors of 196

1 | 2 | 4 | 7 | 14 | 28 | 49 | 98 | 196 

The  ones  that  divide  one but not  both  (not including 144 and 196 )  are
